the bibliography

Table 1 lists all the chromium complexes wbose structures have been determined by X-ray or neutron diffraction and had been published prior to the

middle of 1976. The formulae are expressed in terms of abbreviated ligand codes (e.g. acac, cp), a list of which is given in Table 2 and FlQ. 2. The com-

plexes in Table 1 and the ligands illustrated in Fig. 2 are both ordered according to increasing ligand electro-negativities, starting with pi-complexes and ^ __ rouowed by iigands bonded through C, P, lu’, S, 0 and halogen in that order. This brings chemically similar species together and makes the lists easy to search as well as profitable to browse through. Table 2 lists the ligand codes alphabetically with cross references to Fig. 2 and Table 1.

Method of compilation The information in these tables has been drawn largely from the Organic Crystal Structure Database produced by the Cambridge Crystallographic Data Centre, but it has been supplemented by the addition of 33 carbonyl, cyanide and ammonium complexes that lie outside the range of compounds included in the database. There has been no attempt to include all oxygen, sulphur and halogen complexes. In all other cases the information given in this compilation has been derived directly from the database; only in a few cases was it. necessary to consult the original paper. The editing of the database is sufficiently thorough that it has detected numerical errors in 29 of the 147 original papers that publish complete structural information. In a third of these cases it has been possible to correct the errors. Unfortunately, 49 reports of structure determinations contain no atomic coordinates so that in these cases it is impossible to find out more about the stereo-chemistry than the author has chosen to report. The use of the Cambridge Organic Crystal Structure Database made the preparation of this bibliography remarkably simple. The database, which contains data on all structures containing an organic moiety, was computer searched for compounds containing chromium. StructuraI information (unit

162

cell, atomic coordinates, etc.) for these compounds was automatie~y extracted and used as input to the programs PLOD and GEOM which respectively plot projections of the molecules and print out a comprehensive list of bond lengths and angles. Two or three days work spent in collating these results yielded a collated record of the structti chemistry of chromium compleires that would have taken several weeks of ‘library work to compile by traditional means. Further, this record not only contained a more complete listing of bond distances and angles than was given in the original papers, but was purged of many of the published errors and ambiguities.

The complexes are listed in order of their least electronegative figand. Thus tricarbonylbenzenechromium comes before pe~tac~bo~yltr~phenylphosph~~ chromium and the ethylenediamine complexes follow both. The complex is described by me,ansof a formula using abbreviated ligand names. The chromium complex is always given first in square brackets. Phase information follows the forinula after a hyphen (e.g. “-a” means triclinic form, “-m” means monoclinic form). The alphabetical listing of the ligand abbre~ations is given in Table 2. Following the formula in Table 1 is the formal oxidation state and coordination number of the chromium atom. Since these are not always unambiguous, certain conventions have been adopted for determiniig the formal charge and number of fullctiondl groups of each figand. AlI delocalized or alternating double bond systems pi-bonded to the metal are taken as sing& coordiiating. Likewise C=C groups pi-bonded to the metal are singly coordina&g but other double bonded groups (e.g. As=As and U==O) are taken as bidentate. Nitrosyl is taken to have a formal charge of zero and peroxide of -2. The atoms directly bonded to chromium are listed (CO is listed separately from C) and, for pi-bonded rings, the size of the ring and its heteroatoms (if any) are also given, The stereochemistry is given in part by the order of the figands in the formula (e.g. [(NCS)Z NH3 (NCS)2 NH3 Cr] is the truns isomer, [(NCS)4 (NH312 Cr] is the cis) and by the number of functional groups in polydentate ligands (given under “Geometry”). Thus 22C and 22T refer respectively to the cis and tram isomers of complexes with two bidentate ligands, 33C refers to the ~gement of two tridentate ligands with the three functional groups of each ligand mutually cis, and 33T refers to the arrangement where each tridentate ligand has its three coordinating atoms planar with the metal. The bibliographic data for each complex is given in the.right-hand side of the entry. It starts with a reference to the original publication in the order: journal coden (ASTM standard - see Table 3), volume, page and year of publication. The accuracy of the determination 9~indicated by the following code based on the standard error in the length of a typical C-C bond, or, if this is not available, the crystallographic agreement index, R.

163

1 = Error in C-C < 0.005 a 2 = Error in C-C =G0.010 A or R G 0.05 3=ErrorinC-C< 0.03A orRG0.15 4 = Error in C-C > 0.03 A or R > 0.15 5 = No information on accuracy given. The remaining information refers to the Organic Crystal Structure Database. Class and Refcode refer to the classification and location of the entry in the database. The file status codes have the following meaning: OK = Full error-free structural information available in the database; Error in data = The full structural information is in the file but the original publication contains an error which cannot be corrected; Paper corrected = The &ginal paper contains an error which has been corrected in the database. Equivalent to the status OK; No coordinates in paper = No atomic coordinates were given in the original publication and therefore they are not available in the database; Not in file = Complexes which contain no organic fragment are not included in the Organic Crystal Structure Database. Finally the presence of disorder, the use of neutron diffraction or the determination of the absolute configuration of the complex are noted. Ligand List (Table 2) The ligands are listed in alphabetical order of their abbreviations and include to the left, a number referring to the diagram of the Iigand in Fig. 2 and to the right, the ligand formula, name and reference to the complexes in Table 1 that contain the ligand. For completeness, the list also includes a number of common ligands not found in the chromium complexes. The diagrams in Fig. 2 are illustrated in the following chemical order: Pi-bonded rings ordered according to (i) size of the ring, (ii) heterocycles following homocycles, (iii) number of rings fused to the coordinating ring, (iv) increasing substitution of the ring; other C-Cr pi-bonds; C-Cr sigma-bonds starting with carbonyl then in order of increasing electronegativity of the atoms bonded to C; H-G; Sn-Cr; As--Q; P--X.%; N---Q; S---G; 0-Cr; Halogen-Cr. Polydentate ligands follow the monodentate ligands in the same order, thus tiphenylphosphine, pi-bonding through a phenyl ring as well as sigmabonding through P, follows the mondentate pi-bonded rings, whereas monodentate triphenylphosphine appears with the P-Cr group further down the list. Ligand names are either in the form of mnemonics or formulae. Certain of the mnemonics (e.g. Me, Ph) are written with one upper case and one lower case letter like an element and are used in formulae in the same way as an element symbol_ Other mnemonics (e.g. acac) are written only in lower case and stand alone. In formula names, all numbers are to be read as subscripts (e.g. PPh3 represents PPh, which is the same as P(C,H,),). Bridging ligands

164

have names ending in an asterisk,(e;g, 0’) and those names ending in $1, $2 etc. refer to the same ligand coordinating in different tiays (e.g. “cp” is pibonded cyclopentadienyl; %p.$l” is sigma-bonded cyclopentadienyl), Where available, the bond lengths (in picometres = lo-2 A() found in ehromium complexes are given in Fig. 2. Ah chemiSIy equivalent bonds have been averaged. Where two distances are given, they represent the-range of observed bond lengths. Unless otherwise shown, C-C bonds in alkyl groups are 154 pm and in benzene rings are 142 pm. C-Cr distances to pi-bonded rings lie between 220 and 230 pm, except in sandwich complexes where they are 208-214 pm. Nearly half the complexes contain carbonyl groups which, in spite of the relatively poor accuracy of the structure deprivations, show a marked correlation between the C-0 and Cr-C bond lengths (Fig. I). Fur Cr-G-0 groups tmns to a pi-bonded ring, 0-C = 184 pm, C-0 = Il.5 pm and the Cr-C-0 angle deviates by 3.5” (standard deviation) from 180* (modal angle = 178”). For Cr--C-O groups trans to a CO group the geometry is slightly different. The Cr-C distance is 190 pm, C-0 =t 114 pm and the Cr-C-0 angle deviates from 130” by 5.1” (standard deviation) (modal angle = 176O). In the pentacarbonyls this huger deviation from linearity is associated with a bending of the.equatorial carbonyl groups away from the bulky sixth ligand.
