Abstract
Reaction of the bis(bidentate) ligand 2,5-bis[2-(dimethylamino)phenyl]-1,3,4-oxadiazole (oxanMe) with the precursors trans-[PtMeCl(SMe2)2] and [(PhCN)2PtCl2] afforded the mononuclear complexes [(oxanMe)Pt(Me)Cl] and [(oxanMe)PtCl2], respectively. [(oxanMe)PtMe2] was observed in equilibrium with oxanMe, [Pt2Me4(μ-SMe2)2], and [PtMe2(SMe2)2], but could not be isolated. Reaction of [(oxanMe)PtCl2] with silver acetate gave access to [(oxanMe)Pt(OAc)2] in excellent yield. The latter was treated with [Cu(NCMe)4]BArF, resulting in a disproportionation reaction that afforded the novel trimetallic complex {[(oxanMe)Pt(OOCCH3)2]2Cu}{BArF}2. This complex features a linear PtII–CuII–PtII chain consisting of two Pt→Cu dative bonds supported by two bridging acetate ligands each.
