Bis(2-aminopyridine)(2,2′-bipyridine)platinum(II) tetracyanoplatinate(II) dihydrate

Abstract

In the title compound, [Pt(C10H8N2)(C5H6N2)2][Pt(CN)4]·2H2O, cations and anions alternate along the a axis, giving a one-dimensional chain of the Magnus green salt type. The electrostatic interactions between the divalent cations and anions, together with the π–π stacking associations between the 2,2′-bi­pyridine moieties, contribute to the stabilization of the crystal packing. Two different Pt⋯Pt distances [5.2034 (6) and 4.5599 (6) A] alternate along the one-dimensional stack.
