Far Infrared Spectra

Far-infrared spectra are reported for compounds of formula A3M2X9, with M = Cr, Mo; X = Cl, Br; A = univalent cations, for the region 400-200 cm -1. Assignments for metal-terminal halogen and metal-bridging halogen stretching vibrations in the binuclear anion are proposed. Data on several related mono-nuclear hexahalo complexes are included for comparison. An explanation is offered for differences in the spectral features of the series of compounds in terms of distortions of the binuclear anion which arise from cation-anion interaction in the crystal lattice.

Far Infrared Spectra

Infrared spectra of some triarylphosphine and diphosphine complexes of gallium (III) chloride, bromide, and iodide have been recorded in the range 600–200 cm−1 and assignments of gallium–halogen stretching vibrations made. The number and frequencies of the ν (Ga–X) vibrations are consistent with monomeric structures for the triarylphosphine complexes in the solid state. Possible structures for the diphosphine complexes are discussed.
