Metal complexes of biologically important ligands, LXXXVII α-amino carboxylate complexes of palladium(II), iridium(III) and ruthenium(II) from chloro-bridged ortho-metallated metal compounds and [(OC)3Ru(Cl)(μ-Cl)]2
azobenzene) and [(L)2Ir(μ-Cl)]2 (LH = 2-phenylpyridine) react with α-amino carboxylase to give the N,O-chelate complexes (L)Pd-t-NH2C(H)(R)CO2 and (L)2Ir-NH2C(H)(R)CO2. The chloro-bridged carbonyl complex [(OC)3Ru(Cl)(μ-Cl)]2 and prolinate afford the N,O-chelate (Cl)(OC)3Ru(prolinate). From the osmium complex [(OC)3Os(Cl)(μ-Cl)]2 and N,N-dimethylglycine methylester the ionic compound [HN(Me2)CH2CO2Et]+(Os(CO)3Cl3)−
