Metallkomplexe mit biologisch wichtigen Liganden, XLII [1] Carbonylmetallkomplexe mit Anionen von mehrfunktionellen «-Aminosäuren Metal Complexes with Biologically Important Ligands, X L II [1] Carbonyl Metal Complexes with Anions of Polyfunctional a-Amino Acids

A series of carbonyl metal complexes with anions of functional «-amino acids has been pre­ pared: [M(CO),(L-histidinate)]' (M = Cr, Mo, W), M(CO),(L-histidinate) (M = Mn, Re), [Re(CO)3(NO)(L-histidinate)] + PF6-, M(CO)2(//3-allyl)(L-histidinate) (M = Mo, W), Mo(CO)2(NO)(L-histidinate), [Mo(CO)(NO)(^3-methalIyl)(L-histidinate)]PF6, Mo(CO)2(/73-methallyl)(L-histidineOMe)Cl, [M(CO)3(cysteinate)]2~ (M = Mo, W), [Mo(CO)3(glyglyO)(H2C))]“, [Re(CO)3(L-ornithinate)(CH3CN)] and [Re(CO)3(L-lysinate)]. The IR and NMR data of the new complexes are reported.
