The substitution reactions of the 2,2′-biquinoline (biq) complex cis-[Pd(biq)Cl2] with different amino acids, namely, glycine (glyH), l-serine (serH), l-tyrosine (tyrH), l-phenylalanine (pheH) and l-alanine (alaH) have been investigated. The new complexes [Pd(biq)(gly)]Cl, [Pd(biq)(ser)]PF6·0.5H2O, [Pd(biq)(tyr)2], [Pd(biq)(tyr)]PF6·H2O, [Pd(biq)(phe)2]·2.5H2O, [Pd(biq)(phe)]PF6·H2O and [Pd(biq)(ala)]Cl.1·5H2O have been characterized by elemental analysis, conductivity measurements, IR, electronic absorption and 1H and 13C NMR spectra. Based on these data all amino acid anions are found to act as bidentates except tyrosinate and phenylalanilate which behave also as monodentates.
