Abstract

Single crystals of 1D halogen-bridged binuclear platinum complex, K4[Pt2(pop)4Cl]·3H2O, where pop=P2O5H22-, have been investigated by defused X-ray scattering, reflectivity and luminescence measurements. Compared with the halogen-bridged mononuclear metal complexes, several unusual behaviors are observed, which are responsible for an additional charge modulation in the charge density wave state. From the viewpoint of the extended Peierls-Hubbard model, they are reduced to the result of a competition between the electron-electron repulsive energy in binuclear Pt-Pt sites and the energy gain due to chlorine ion displacement.
