Linear, Redox‐Active Pt₆ and Pt₂Pd₂Pt₂ Clusters

Abstract

A piece of jewelry is the complex [Pt4M2(μ-H)(μ-dpmp)4(XylNC)2](PF6)3 (M=Pt, see structure), which contains the longest platinum chain characterized so far. This complex and the related compound with M=Pd are redox-active and can be readily oxidized to the electron-deficient clusters [Pt4M2(μ-dpmp)4(XylNC)2](PF6)4 (M=Pt, Pd) with dynamic structural changes in the metal strings. Xyl=2,6-dimethylphenyl, dpmp=bis(diphenylphosphanylmethyl)phenylphosphane.
