A piece of jewelry is the complex [Pt 4 M 2 (μ‐H)(μ‐dpmp) 4 (XylNC) 2 ](PF 6 ) 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 [Pt 4 M 2 (μ‐dpmp) 4 (XylNC) 2 ](PF 6 ) 4 (M=Pt, Pd) with dynamic structural changes in the metal strings. Xyl=2,6‐dimethylphenyl, dpmp=bis(diphenylphosphanylmethyl)phenylphosphane.
