Abstract

The IR, XPS and resonance Raman spectra of a series of Ni-Pd mixed-metal MX-chain compounds, Ni_1-xPd_x(chxn)₂Br₃ have been measured in order to investigate the competition between the electron-correlation in Ni^III and the electron-phonon interaction in Pd^II-Pd^IV states. The splitting of doublet signals of the Pd^II-Pd^IV in IR spectra and the integrated intensity of the Pd^IV-Br stretching in Raman spectra decrease with decrease of Pd components. These results suggest that the Pd^II-Pd^IV mixed-valence states are effectively influenced by Ni^III states, approaching toward the Pd^III states.
