Abstract
A series of single crystals of quasi-one-dimensional halogen-bridged Ni-Pd mixed-metal compounds, Ni1-xPdx(chxn)2Br3 (chxn=1R,2R-cyclohexanediamine) have been obtained by electrochemical oxidation methods. In order to investigate the competition between the electron-correlation in the NiIII states (SDW states) and the electron-phonon interaction in the PdIIPdIV mixed-valence states (CDW states) in the Ni-Pd mixed-metal compounds, the single-crystal electrical conductivities, IR, resonance Raman spectra, ESR, magnetic susceptibilities, and XPS, have been measured. The electrical conductivities of these compounds show semiconducting behavior with the conductivities maximized and the activation energies minimized at x=ca. 0.5. The IR, resonance Raman spectra, and XPS show that the pdII-pdIV mixed-valence states are influenced and approaching to the PdIII states with the increase of the NiIII components.
