A series of palladium(II) and platinum(II) complexes Cl2M(P-N-O) (M = Pd, Pt) with bidentate Schiff bases (P-N-O) from 2-(diphenylphosphino)benzaldehyde and α-amino acid esters has been synthesized, using PdCl2 or K[PtCl3(C2H4)], respectively. Abstraction of chloride from Cl2M(P-N-O) (using AgBF4) has afforded the cationic complexes [(P-N-O)M(Cl)]+BF4− in which the Schiff bases function as tridentate ligands with coordination of the ester group. The structures of Cl2Pd(Ph2PC6H4C(H)=N-CH2CO2Et) and of [(Cl)Pd(Ph2PC6H4C(H)=NC(H)(CH2CH=CH2)CO2Me)]+BF4− have been determined by X-ray diffraction. Complexes (L)MCl2 and [(L)MCl]+BF4 (M = Pd, Pt) have also been prepared with the reduced Schiff base Ph2PC6H4CH2NHC(H)(CH2Ph)CO2Me.

The reactions of the chlorido-bridged complexes [Cp*M(Cl)(μ-Cl)]2 (M = Rh, Ir) with Schiff bases (P-N-O) from 2-(diphenylphosphino)benzaldehyde and α-amino acid esters afford the complexes Cp*M(Cl)2(P-N-O) in which the ligands function as monodentate P donors (M = Ir) or as bidentate P-N donors (M = Rh). These complexes can be converted into cationic complexes [Cp*M(Cl)(P-NO)]+ with bidentate P-N ligands by treatment with NH4PF6. The cationic complexes [Cp*M(Cl)(PN- O)]+Cl− have been detected also in solutions of Cp*M(Cl)2(P-N-O). The P-N-coordinated complex [Cp*Rh(Cl)(Ph2P-C6H4-C(H)=N-C(H)(CH2Ph)CO2Me)]+PF6− was characterized by X-ray diffraction. From Cp*M(Cl)2(P-N-O) and AgBF4 or AgPF6 (molar ratio 1 : 2) the dicationic complexes [Cp*M(P-N-O)]2+ are formed in which the ester group is also coordinated to the metal atom. The Schiff base from 2-(diphenylphosphino)benzaldehyde and allylglycine ester acts as a tridentate ligand, however with coordination of the C=C allyl group instead of the ester function.
