Abstract: Reactions of Pt (MeNH2)2(H2O)22+ with glycine,L-methionine, N-methyliminodiacetie acid and thiodiacetic acid were studied by pH potentiometry and 13C NMR spectroscopy.The complex formation constants (logK) were 8.55, 8.64,8.05 and 3.68, respectively, as determined by pH titration at 37℃. The possible structures of the formed complexes were briefly discussed.

Key words: amino acid, platinum, complex, coordination effect
