Constructing highly conducting metal-metal bonded solids by electrocrystallization of [Pt(II)2(RCS2)4] (RCS2(-) = dithiocarboxylato, R = methyl or ethyl).

Partially oxidized one-dimensional (1D) Pt-Pt chain compounds [Pt2(MeCS2)4]4ClO4.5PhCN (1) and [Pt2(EtCS2)4]5(ClO4)2 (2) were synthesized by electrocrystallization of diplatinum(II,II) complexes from different solvents. 1 and 2 consist of 1D Pt-Pt chains of stacked Pt-Pt dimers with short interdimer S.
