Self-selected formation of a heteropolymetallic sandwich [Pd3Pt4(μ3-S)4(μ-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).
