Abstract :
A series of single crystals of quasi-one-dimensional chloro-bridged Ni–Pd mixed-metal MX-chain compounds, Ni1−xPdx(chxn)2Cl3 (chxn=1R,2R-diaminocyclohexane) have been obtained by electrochemical oxidation methods. In order to investigate the competition between the electron correlation in the Ni(III) states and the electron–phonon interaction in the Pd(II)–Pd(IV) mixed-valence states in the Ni–Pd mixed-metal compounds, the infrared spectra, resonance Raman spectra, X-ray photoelectron spectra and Auger spectra have been measured. These results show that the Pd(II)–Pd(IV) mixed-valence states are influenced by Ni(III) and gradually approaching to the Pd(III) states with the increase of the Ni(III) components as observed in Br-bridged complexes, Ni1−xPdx(chxn)2Br3.
