摘要：

Resistance measurements under uniaxial compression have been performed on the quasi-one-dimensional iodo-bridged diplatinum complex (MMX-chains) Pt-2(n-butylCS(2))(4)I between 100-355 K. The first-order phase transition between the low-temperature alternate-charge-polarization (ACP) state and room-temperature average-valence (AV) state (210K at ambient pressure) shifted to a higher temperature under compression both parallel and perpendicular to the MMX chains. The stabilization of the ACP state by both compression directions indicates that the ligand molecules play a significant role in making the valence ordering state.
