| Abstract: | Varieties of quasi-one-dimensional halogen (X)-bridged transition-metal (M) complexes, (C_{8}H_{6}N_{4})×[Pt(C_{2}H_{8}N_{2})X]_{2}X(ClO_{4})_{3}・H_{2}O (X=Br,Cl) and (C_{10}H_{8}N_{2})[Pt(C_{4}H_{13}N_{3})Br]_{2}Br_{4} ・2H_{2}O, comprising two-leg ladders of mixed-valent platinum ions, are described in terms of a multiband extended Peierls-Hubbard Hamiltonian. The polarized optical-conductivity spectra are theoretically reproduced, and the ground-state valence distributions are reasonably determined. The latter variety, whose interchain valence arrangement is out of phase, is reminiscent of conventional MX single-chain compounds, while the former variety, whose interchain valence arrangement is in phase, reveals itself as a d-p-π-hybridized multiband ladder material. |
