Electronic influences on metallophilic interactions in [Pt(tpy)X][Au(C6F5)2] double salts.

Four double salt compounds of the type [Pt(tpy)X][Au(C(6)F(5))(2)], where tpy =2,2':6',2''-terpyridine and X = Cl, 3, Br, 4, I, 5, and CCPh, 6, and their platinum starting materials, [Pt(tpy)Br]Br·2H(2)O, 1, and [Pt(tpy)(CCPh)]PF(6)·DMF·H(2)O, 2, have been synthesized and characterized. Complex 2 is a solvated form of the known and structurally characterized [Pt(tpy)(CCPh)]PF(6) species. All compounds were characterized by single-crystal X-ray diffraction, elemental analyses, and solution electronic spectra.
