Abstract :
The IR, XPS and resonance Raman spectra of a series of Ni-Pd mixed-metal MX-chain compounds, Ni1−xPdx(chxn)2Br3 have been measured in order to investigate the competition between the electron-correlation in NiIII and the electron-phonon interaction in PdII–PdIV states. The splitting of doublet signals of the PdII–PdIV in IR spectra and the integrated intensity of the PdIV-Br stretching in Raman spectra decrease with decrease of Pd components. These results suggest that the PdII–PdIV mixed-valence states are effectively influenced by NiIII states, approaching toward the PdIII states.
