Abstract

A reaction of cu-PtCl2(DMSO)2 (DMSO = dimethyl sulfoxide, C2H6OS) with 2,3,5,6-tetrakis(2-pyridyl) pyrazine (tpp, C24H16N6) gave the title salt, [Pt2Cl2(μ-tpp)][PtCl3(DMSO)]2. The compound consists of a dinuclear Pt cation, [Pt2Q 2(μtpp)]2+, and two [PtCl3(DMSO)] - anions. The two Pt atoms within the cation are separated by a distance of 6.4792 (17) Å, and their coordination planes are canted at an angle of 19.6 (9)°. The shortest intermolecular Pt⋯Pt distance is 4.5726 (16) Å. Metal-metal interactions are unimportant in the crystal structure, and the packing is stabilized by extensive π-π interactions between the tpp moieties, in addition to ionic interactions.
