Visible and Far Infrared Spectral Studies of Tetrahedral and Octahedral Complexes in Non-Aqueous Solvent Systems. Part I: Far Infrared Spectra of Tetrachlorometallates (MCl4(-X)) IN Benzene

摘要

Several tetrachlorometallate (MCl4(-x)) complexes were prepared in benzene by reacting the solid metal salts with a solution of a long-chain, high molecular weight quaternary salt or an amine hydrochloride. The resulting complexes have been studied by far infrared spectrometry. Evidence of cation effects on the distortion of the anion have been observed. Force constant calculations have been carried out assuming a Urey-Bradley force field. For the complexes of the first row transition metals, the M-Cl force constants (stretch) are in the order MnNiGa>In as one would expect. (Author)
