Self-selected formation of a heteropolymetallic sandwich [Pd3Pt4(micro3-S)4(micro-dppy)4(dppy)4][PF6]3 from dinuclear addition across the [Pt2] and [Pd2] cores (dppy = 2-(diphenylphosphino)pyridine)

Abstract

The high reactivity of Group 10 metal-metal bonded complexes towards platinum chalcogenide compounds have been demonstrated through the successful isolation of a number of novel homo- and hetero-polynuclear complexes. A d8-d9 pentanuclear sulfide cluster with a Pd3 triangle sandwiched by two Pt2 sheaths with peripheral protection from coordinated and pendant pyridyls has been isolated and characterized. Other related aggregates with the [Pt2M2X2] (X = S, Se) core have also been obtained from the addition of the [Pt2S2] metalloligand to dinuclear Pd(I).
