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.
