Abstract
The resistivity of four one-dimensional halogen-bridged metal complexes, Pt2(CH3CS2)4I and M(chxn)2X3 (M = Ni, Pd, Pt; X = Br; I; chxn = 1R, 2R-cyclohexanediamine), has been studied up to 7 GPa under quasi-hydrostatic conditions. The resistivity of Pt2(CH3CS2)4I and Ni(chxn)2Br3 with regular chains monotonically decreased with increasing pressure. On the other hand, the resistivity of Pd(chxn)2Br3 and Pt(chxn)2I3 with alternating lienar chains rapidly decreased in the low pressure region. The activation energy of the four metal complexes was in the range 0.03-0.05 eV at 7 GPa. Metallic behavior was not observed even at high pressures. The electrical conduction of the complexes is discussed.
