Vibrational spectroscopic study of some benzonitrile complexes of antimony pentachloride

Article abstract of DOI:10.1016/0584-8539(84)80159-2

Complexes of antimony pentachloride were prepared with benzonitrile, 2,3- and 4-methyl-benzonitriles, and 2,3-; 2,4-; 2,5- and 3,4-dimethylbenzonitriles of type SbCl5.L.All the isolated solids were non-electrolytes in nitromethane.The i.r. and Raman spectral data of the complexes are in good agreement with local C_4v symmetry for the SbCl5N moiety.A classification of the donor strength of benzonitriles is proposed.
