Abstract The partially oxidized cis-Pt(NH3)2(SCN)2I has been studied by resonance Raman spectroscopy. A progression in the symmetric I-PtIV-I vibration (v1 = 120.1 cm-1), reaching as far as 8 v1, has been observed. The compound Pt(NH3)2(SCN)2I could be identified as a mixed valence solid with neutral, linear PtII···I-PtIV chains.

Abstract The electronic and resonance Raman spectra of new mixed-valence compounds of the type M2ʹ[M(L)X3][M(L)X5], where Mʹ = K, NH4, M = Pt or Pd, L = NH3 or pyridine, and X = Cl, Br or I, have been studied. The single-crystal polarized reflectance spectra indicate the one-dimensional semiconductor behaviour. The polarized resonance Raman spectra confirm the --M(II)--X-M(IV)-X linear chain structure, which is in accordance with the X-ray results. The polarization of M-N bands can be explained by the Snyder's theory (1971).
