Structure and Redox Behaviour of a Paramagnetic Rh–Pt–Cu–Pt–Rh Heterometallic- Extended Metal -Atom Chain

A paramagnetic, pentanuclear, metal–metal bonded complex comprising three metals is isolated. The Cu d x 2 − y 2 orbital of the Rh–Pt–Cu–Pt–Rh chain contains an unpaired electron. The close energetic levels and symmetric overlap...
