metal-organic compounds
In the title compound, [PtI(C15H11N3)][AuI2], the [PtI(terpy)]+ cations (terpy is 2,2′:6′,2′′-terpyridine) stack in pairs about inversion centers through PtPt interactions of 3.5279 (5) Å. The [AuI2]− anions also exhibit pairwise stacking, with AuI distances of 3.7713 (5) Å. The [PtI(terpy)]+ cations and [AuI2]− anions aggregate forming infinite arrays of stacked ({[PtI(terpy)]+[PtI(terpy)]+}{[AuI2]−[AuI2]−}) units.
