Rhodium complexes by a bridging

Modification of Metal-Metal Bonding in Rhodium Complexes by a Bridging Pi phosphine. The yellow, planar complexes, (RNC)i,Rh+, undergo novel self-association reactions in concentrated solution to form the blue or violet dimers, (RNC)8Rh22+, via reaction (1) (1,2). The equilibrium constants for this reaction are strongly...
