Resonance Raman spectrum of the mixed-valence anion-bridged complex Cs2[Pt(NO2)(NH3)Br2][Pt(NO2)(NH3)Br4]

Abstract

The resonance Raman spectrum of the title complex with 568·2 nm excitation consists of eleven three-or-more-membered progressions, in nine of which the ν1, ν(BrPtIVBr), acts as the progression-forming mode; the results yield (among others)ω1= 179·0 ± 0·3 cm–1, x11=–0·39 ± 0·04 cm–1, and imply a substantial change in the PtIV–Br chain bond length (along with other structural changes) on excitation of the complex from the ground to the resonant (intervalence) excited state.
