| dc.description.abstract | Reactions of the dimers [{(eta(5) -C5Me5)MCl(mu-Cl)}(2)] (M = Rh, Ir) with the ligand NMe(PPh2)(2) in 1:2 molar ratio afford the mononuclear cationic complexes [(eta(5)-C5Me5)MCl{eta(2)-P,P'-(Ph2P)(2)NMe}]Cl (M = Rh 1, Ir 2). Similar iodide complexes, [(eta(5)- C5Me5)MCl{eta(2)-P,P'-(Ph2P)(2)NMe}]I (M = Rh 3, Ir 4), can be prepared by N-functionalization of co-ordinated dppa ligand in complexes [(eta(5) -C5Me5)MCl{eta(2)-P,P'-(Ph2P)(2)NH}]BF4. The tetrafluoroborate derivatives, [(eta(5)-C5Me5)MCl{eta(2)-P,P'- (Ph2P)(2)NMe}]BF4 (M = Rh 5, Ir 6) are prepared by reaction of complexes 1-4 with AgBF4 in acetone. All the compounds described are characterised by microanalysis, IR and NMR (H-1, P-31{H-1}) spectroscopy. The crystal structure of complex 5 is determined by X-ray diffraction methods. The complex exhibits a pseudo-octahedral molecular structure with a C5Me5 group occupying three co-ordination positions and a bidentate chelate P,P'-bonded ligand and a chloride atom completing the coordination sphere.
