Abstract

Linear-chain iodo-bridged dinuclear Pt mixed-valence compounds with aromatic ammonium countercations, A₄[Pt₂I-(pop) ₄]·nH₂O [pop = P₂O₅H ₂^2-, A = benzyl ammonium (n = 2; 1), anilinium (n = 2; 2), and p-methoxy anilinium (n = 2; 3)], that have three-dimensionally ordered structures were synthesized. In the case of 1-3 the aromatic ammonium countercations were located between neighboring Pt chains and stacked in 1D columns. π-π Interactions between the phenyl rings and hydrogen bonds between the -NH₃⁺ moieties and the oxygen atoms of the pop ligand link the Pt chains together, thus giving rise to a three-dimensionally ordered CDW state. This is the first observation of this phenomenon in compounds of this type.
