Abstract
The complex [Rh(µ-pz)(CO)(pcBr)]2[pz = pyrazoly, pcBr = P(o-BrC6F4)Ph2] undergoes orthometallation in refluxing toluene to give a new binuclear compound containing a rhodium–rhodium bond, Rh2 Rh2(µ-pz)2(µ-pc)Br(CO)(pcBr)[pc = P(C6F4)Ph2], which has been structurally characterized by X-ray crystallography; the complex has two pyrazolyl groups and one orthometallated phosphine bridging the two in equivalent rhodium atoms, and one phosphine ligand chelating one of the rhodium atoms via P and the bromine atom from the o-bromotetrafluorophenyl group.Keywords
