The systematic synthesis of heterobimetallic complexes with only one bridging Ph2PCH2PPh2(dppm) ligand: crystal structures of [(OC)4Fe(µ-dppm)RhCl(CO)] and [(OC)3Fe(µ-dppm)(µ-CO)PtBr2]
Abstract
[(OC)4Fe(dppm-P)](dppm = Ph2PCH2PPh2) reacts with [RH2Cl2(CO)4] to give [(OC)4Fe(µ-dppm)RhCl(CO)] with an Fe-Rh bond but no bridging carbonyl group; with [PtBr2(cyclo-octa-1,5-diene)] the product [(OC)3Fe(µ-dppm)(µ-CO)PtBr2] shows some bridging interaction of one of the carbonyl ligands.
