Vibrational spectra of metal-nitro complexes. II. Substituted halo complexes of platinum(IV)

Abstract

The infrared and Raman spectra of compounds forming the series given by [Pt(NO₂)_6-nCl_n]^2- (n = 0-5) together with some of the analogous bromo and iodo compounds have been obtained. Most compounds were studied in the solid state, but the Raman spectra of solutions of some of the compounds were also obtained. The spectra were interpreted initially by considering the likely point group symmetry of the complex ion. Where details of the crystal structures were known, the site group and factor group symmetries were also considered.
