The salts [Pt{C(NHMe)(2)}(4)][Au(CN)(2)](2), [Pt{C(NHMe)(2)}(4)][Ag-2(CN)(3)][Ag(CN)(2)], [Pt(en)(2)][Au(CN)(2)](2), [Pt(en)(2)][Ag(CN)(2)](2), and [Pt(biPY)(2)][Au(CN)(2)](2) have been prepared by mixing solutions of salts containing the appropriate cation with solutions of K[Au(CN)(2)] or K[Ag(CN)(2)]. Because the platinum atom in the cation is sterically protected, the structures of [Pt{C(NHMe)(2)}(4)][Au(CN)(2)](2) and [Pt{C(NHMe)(2)}(4)][Ag-2(CN)(3)][Ag(CN)(2)] reveal no close metal-metal interactions. Colorless crystals of [Pt(en)(2)][Au(CN)(2)](2) and [Pt(en)(2)][Ag(CN)(2)](2) are isostructural and involve extended chains of alternating cations and anions that run parallel to the crystallographic a axis, along with isolated anions. In the chains, the metal-metal separations are relatively short: Pt... Au, 3.1799(3) &ANGS;; Pt...Ag, 3.1949(2) &ANGS;. In [Pt(biPY)(2)]-[Au(CN)(2)](2), each cation has axial interactions with the anions through close Pt... Au contacts [3.1735(6) &ANGS;]. In addition, the anions are weakly linked through (AuAu)-Au-... contacts of 3.5978(9) &ANGS;. Unlike the previously reported Pt/Au complex [Pt(NH3)(4)][Au(CN)(2)](2)(.)1.5H(2)O, which is luminescent, none of the salts reported here luminesce.
