o-Fluorophenyl glycine and alanine, 2-thienyl glycine and alanine form with dinuclear, chloro bridged metal complexes the chiral N,0-chelates (arene)M(Cl)(NH2CHRCO2) (M = Ru, Rh, Ir; arene = cymene, Cp*) and (R3P)(Cl)M(NH2CHRCO2) (M = Pd, Pt) as mixtures of diastereoisomers or cis/trans-isomers, respectively.
