Metallophilic interactions in iodido(2,2′:6′,2′′-terpyridine)platinum(II) diiodidoaurate(I)

In the title compound, [PtI(C(15)H(11)N(3))][AuI(2)], the [PtI(terpy)](+) cations (terpy is 2,2':6',2''-terpyridine) stack in pairs about inversion centers through Pt...Pt interactions of 3.5279 (5) A. The [AuI(2)](-) anions also exhibit pairwise stacking, with Au...I distances of 3.7713 (5) A. The [PtI(terpy)](+) cations and [AuI(2)](-) anions aggregate forming infinite arrays of stacked ...([[PtI(terpy)](+)...[PtI(terpy)](+)]...[[AuI(2)](-)...[AuI(2)](-)])... units.
