摘要：

The coordination behaviour of the heterofunctional phosphine ligand PPh2NHC(O) Me towards Rh(I) is reported and examples of neutral and cationic complexes containing mono- or bi-dentate modes of coordination are found. The X-ray structure of [Rh{PPh2NHC(O) Me}(CO) Cl].CH2Cl2 (1.CH2Cl2) shows that the P,O-chelate is almost planar and coplanar with the Rh(I) square-plane. An unusual example of coordination is found in the dimer [Rh{mu-PPh2N-C(-O) Me}(CO)](2) ( 2), which contains the bidentate, anionic ligand that bridges two rhodium atoms via the oxygen; it is probable that the neutral ligand can form similar complexes, such as 11 and 12. Displacement of the P, O ligand by CO or RNC ligands occurs in 1 but not in 2.
