Abstract

In the title compound, [Pt2(μ-C13H 14N3O)2(NH3)4](ClO4) 6·2H2O, the dinuclear PtII cation is found to be a head-to-tail isomer having pseudo-C2 symmetry. Two positively charged viologen moieties tethered to the diplatinum unit are located at the farthest position to minimize the electrostatic repulsion between the moieties, and also serve as relatively strong electron-withdrawing groups, giving rise to a very long intradimer Pt⋯Pt distance [3.0852 (13) Å] which is the longest distance among those reported for amidate-bridged cis-diammineplatinum(II) dimers to date.
