Abstract

Variable temperature 13C and 31P NMR studies on Rh6(CO)12[P(OPh)3]4 show that the solid state structure is maintained in solution from -80 to 60°C. Above 60°C there is a fluxional motion of some of the carbonyls between triply-bridging and edge-bridging positions. The onset of this fluxionality parallels the appearance of catalytic activity in hydrogenation of cyclohexene.
