Based on a symmetry argument, we investigate the ground-state properties of newly synthesized metal–halide ladder compounds (C 8 H 6 N 4 )[Pt(C 2 H 8 N 2 ) X ] 2 (ClO 4 ) 4 ·2H 2 O ( X =Cl, Br, and I). Employing a fully dressed two-band Peierls–Hubbard model, we systematically reveal possible charge- or spin-ordered states. Numerical phase diagrams demonstrate a variety of competing Peierls and Mott insulators with particular emphasis on the transition between two types of mixed-valent state of… Expand

Neutral-Type One-Dimensional Mixed-Valence Halogen-Bridged Platinum Chain Complexes with Large Charge-Transfer Band Gaps.
TLDR
The relationship between the intervalence charge-transfer (IVCT) band gap and the degree of distortion of the 1D chain shows that the neutral MX chains have a larger IVCT band gap than that of cationic MX-chain complexes. Expand
A Mixed-Valent Metal-Organic Ladder Linked by Pyrazine.
TLDR
The MOL was found to have an electronic state that corresponds to the mixed-valence state of PtII and PtIV, and the intervalence charge transfer energy of the MOL has lower than that expected from the tendency of a similar halogen-bridged mixed-Valence MOL owing to its unique "zig-zag"-shaped legs.
