Abstract
Redox-related [OsIV 2Br9]– and [OsIII 2Br9]3– have been isolated and characterised for the first time, initially as tetra(n-butyl)ammonium salts, and compared with face-sharing [Ru2Br9]z–(z= 1, 2, 3) and edge-sharing [Os2X10]z–(X = Br, Cl; z= 2, 3, 4), by voltammetry and by spectroscopic studies which include the electrogenerated mixed-valence complexes, [Os2Br9]2– and [Os2Br10]3–.Keywords
