The sensor 1 can detect fluoride ion selectively through visual color change. Moreover, insitu cyclization of sensor 1 to benzimidazole derivative 2 takes place by fluoride ion as evidenced by X-ray crystal structure.
New organoarsine containing anthraquinone-based open bipodand ligand and its Pd(II) complex have been synthesized and characterized. X-ray structures of complex shows that the ligand chelates with Pd(II) and formed a 14 membered palladacycle. One of the palladium complex reported here serves as a catalyst for the Heck reaction. Electrochemical behaviors of new compounds versus Ag/AgCl are also discussed.

Five new pseudooctahedral nickel(II) complexes have been prepared, structurally and magnetically characterized. For three complexes the zero-field splitting parameter D has been extracted from SQUID measurements and correlated with the structural tetragonality parameter Dstr. These complexes span the prediction interval of the previously published correlations and confirm the assumption that the negative ZFS parameter D of the Ni(II) can be tuned by the tetragonal compression of the pseudooctahedral chromophore.

We report five novel extended supramolecular polymers based on CuSCN and 1,n-bis(4-methylpyridine)alkane cations. Compounds 1, 2, 3 and 5 possess the infinite two-dimensional polypseudorotaxane anion networks. Compound 4 has a novel 1D chain structure which looks like lotus root.
The electrochemical behavior of a series of Ru(II)-diimine complexes is discussed. In particular, electrochemical techniques were use to evaluate the binding to bovine serum albumin of two model complexes. Moreover, evidence for differential intercalation of the model complexes with DNA is presented.
[FeIII(Him)2(3-MeOsalen)]ÆH2OÆEtOHÆX (Him = imidazole, 3-MeOsalen = N,N0 -bis(3- methoxysalycilidene) ethylenediaminato, and X = PF6, AsF6, SbF6), were synthesized in ethanol. The FeIII ion has an octahedral coordination geometry with N2O2 donor atoms of the planar tetradentate ligand (3-MeOsalen) and two nitrogen atoms of two imidazoles at the axial positions. Through H2O and EtOH the complex-cations are assembled into a hydrogen-bonded 2D network structure and the anion X is accommodated in the void of the 2D network. The temperature dependences of the magnetic susceptibilities revealed an abrupt and two-step spin transition with a small thermal hysteresis for the PF6 and AsF6 salts.
A combination of structural, spectroscopic and theoretical (DFT) calculations of a simple tridentate O,N,O donor Schiff base ligand and its cobalt complexes in different oxidation states have been reported. Multifunctional material properties (both in solid and solution state) have been intensely explored for those materials.

In addition to grinding 1a, mechanochemical reaction is another way to synthesis 1b. Mechanochemical reaction of [Pb(Br)2(4,40 bipy)]n and [Pb(I)2(4,40 -bipy)]n with KCl was not resulted in formation of 1 polymorphs.
Compound [Ru3O(CH3COO)6(3-pic)2(NO)] PF6 (1) (3-pic = 3-picoline), proposed as a new NO donor, and its characterization are presented. Compound 1 releases NO under physiological pH within visible region irradiation (532 and 660 nm) and acts as a vasorelaxing agent, promoting 89% of relaxation in pre-contracted rat aorta under ambient light exposure.
New amino-azo-phenol complexes of Pd(II) and Ru(II) were synthesized and unequivocally characterized. The palladium complexes exhibited catalytic activities toward C–C, C–N coupling and cyanation whereas the ruthenium complexes are active transfer hydrogen catalyst.
A facile method for synthesis of palladium nanocatalyst on amino-vinyl functionalized Fe3O4 magnetic nanoparticles was introduced. The catalytic activity of supported palladium nanocatalysts was investigated in Heck coupling reactions of a series of aryl halides and olefins.

A new set of ruthenium(III) aroylhydrazone complexes have been reported with their crystal structure. Their DNA/protein binding studies indicated a strong interaction with the biomolecules. In vitro cytotoxicity analyses done with A549 cell lines established the anticancer potential of the complexes 1 and 2.
Five new complexes were synthesized using 2-(1H-1,2,4-Triazol-3-yl)pyridine as ligand. New Y(III), Sm(III), Eu(III), Gd(III) and Tb(III) complexes were obtained. Elemental analysis, TG, FT-IR, P-XRD, mass and fluorescence spectroscopy were performed. A general structure of the new photoluminescent complexes was suggested. The obtained complexes present remarkable photoluminescent properties.
Two new Cu(II) complexes were synthesized from dimeric mono- and dipyrrole-polyamides tethered with carboxylate-containing linkers and found to exhibit high DNA-cleaving activities under physiological conditions, presumably via an oxidative mechanism. In addition, both complexes showed moderate inhibitory activities toward HepG2 and A549 cells.

A truncated series of ruthenium(IV) complexes [RuCl(6n)(RCN)n]n2 (n = 0–3; R = n-propyl) has been electrogenerated in situ and characterized spectroscopically. The Cl fi Ru4+ charge transfer manifold red-shifted from n = 0–2, and then moved back to the blue edge upon the third substitution of chloride with nitrile. The irregular trends contradict the results of the DFT studies and the tenet of ligand additivity principle.
In compound 1, the [PMo12O40]3 are encapsulated in the supramolecular cages formed by ligands, and the ligands are protonated as H2L and HL. There is no covalent bonds between POMs and ligands. The result shows that the charge of compound 1 is balanced by the ligands, then the whole structure become neutral and stable. The interaction from the intermolecular hydrogen bonds plays an important role in the formation of the whole framework.
The lowest energy (C6H6)Co2(CO)n structures (n = 6, 5, 4, 3) by at least 8 kcal/mol all have cis geometries with intact benzene rings and Co–Co bonds.

Five new pseudooctahedral nickel(II) complexes have been prepared, structurally and magnetically characterized. For three complexes the zero-field splitting parameter D has been extracted from SQUID measurements and correlated with the structural tetragonality parameter Dstr. These complexes span the prediction interval of the previously published correlations and confirm the assumption that the negative ZFS parameter D of the Ni(II) can be tuned by the tetragonal compression of the pseudooctahedral chromophore.

We report five novel extended supramolecular polymers based on CuSCN and 1,n-bis(4-methylpyridine)alkane cations. Compounds 1, 2, 3 and 5 possess the infinite two-dimensional polypseudorotaxane anion networks. Compound 4 has a novel 1D chain structure which looks like lotus root.
The electrochemical behavior of a series of Ru(II)-diimine complexes is discussed. In particular, electrochemical techniques were use to evaluate the binding to bovine serum albumin of two model complexes. Moreover, evidence for differential intercalation of the model complexes with DNA is presented.
[FeIII(Him)2(3-MeOsalen)]ÆH2OÆEtOHÆX (Him = imidazole, 3-MeOsalen = N,N0 -bis(3- methoxysalycilidene) ethylenediaminato, and X = PF6, AsF6, SbF6), were synthesized in ethanol. The FeIII ion has an octahedral coordination geometry with N2O2 donor atoms of the planar tetradentate ligand (3-MeOsalen) and two nitrogen atoms of two imidazoles at the axial positions. Through H2O and EtOH the complex-cations are assembled into a hydrogen-bonded 2D network structure and the anion X is accommodated in the void of the 2D network. The temperature dependences of the magnetic susceptibilities revealed an abrupt and two-step spin transition with a small thermal hysteresis for the PF6 and AsF6 salts.
A combination of structural, spectroscopic and theoretical (DFT) calculations of a simple tridentate O,N,O donor Schiff base ligand and its cobalt complexes in different oxidation states have been reported. Multifunctional material properties (both in solid and solution state) have been intensely explored for those materials.

A new set of ruthenium(III) aroylhydrazone complexes have been reported with their crystal structure. Their DNA/protein binding studies indicated a strong interaction with the biomolecules. In vitro cytotoxicity analyses done with A549 cell lines established the anticancer potential of the complexes 1 and 2.
Five new complexes were synthesized using 2-(1H-1,2,4-Triazol-3-yl)pyridine as ligand. New Y(III), Sm(III), Eu(III), Gd(III) and Tb(III) complexes were obtained. Elemental analysis, TG, FT-IR, P-XRD, mass and fluorescence spectroscopy were performed. A general structure of the new photoluminescent complexes was suggested. The obtained complexes present remarkable photoluminescent properties.
Two new Cu(II) complexes were synthesized from dimeric mono- and dipyrrole-polyamides tethered with carboxylate-containing linkers and found to exhibit high DNA-cleaving activities under physiological conditions, presumably via an oxidative mechanism. In addition, both complexes showed moderate inhibitory activities toward HepG2 and A549 cells.

In acetonitrile solution, complex 1 did not react with nitric oxide gas. Addition of nitric oxide gas to the acetonitrile solution of complex 2 resulted in unstable Mn(II)-nitrosyl intermediate prior to the reduction of Mn(II) to Mn(I) with a simultaneous N-nitrosation of the ligand.

A truncated series of ruthenium(IV) complexes [RuCl(6n)(RCN)n]n2 (n = 0–3; R = n-propyl) has been electrogenerated in situ and characterized spectroscopically. The Cl fi Ru4+ charge transfer manifold red-shifted from n = 0–2, and then moved back to the blue edge upon the third substitution of chloride with nitrile. The irregular trends contradict the results of the DFT studies and the tenet of ligand additivity principle.
In compound 1, the [PMo12O40]3 are encapsulated in the supramolecular cages formed by ligands, and the ligands are protonated as H2L and HL. There is no covalent bonds between POMs and ligands. The result shows that the charge of compound 1 is balanced by the ligands, then the whole structure become neutral and stable. The interaction from the intermolecular hydrogen bonds plays an important role in the formation of the whole framework.
The lowest energy (C6H6)Co2(CO)n structures (n = 6, 5, 4, 3) by at least 8 kcal/mol all have cis geometries with intact benzene rings and Co–Co bonds. However, the perfluoro and trifluoromethyl systems have ‘‘flyover’’ derivatives with acyclic rather than cyclic C6R6 ligands as the lowest energy structures for (C6R6)Co2(CO)n (n = 4, 3).

Inorganica Chimica Acta 429 (2015) 237
Syntheses, characterisations and catalytic epoxidation activities of dithiocarbamate complexes containing ruthenium were described. The epoxidation of cis-cyclooctene, using PhIO as primary oxidant, is shown to be dependent on the lability of biphosphine in the catalyst precursor, followed by its oxidation. The X-ray structures of [Ru(dppb)(pipeCS2)2] (1), [Ru(dppb)(morphCS2)2] (2) and [Ru(dppb)(ethCS2)2] (3) were determined.
