Abstract

Abstract: A series of N-alkyl iminodiacetato (diammine) Platinum (Ⅱ) complexes[Pt(NH₃)₂(R-N(CH₂COO)₂], R=Me, i-Pr, n-Pr, HO-Et] have been synthesized under different pH conditions.The results of ¹³C NMR study (20MHz) show that the iminodiacetate ligands are coordinated to platinum through N, O linkages, which doesn't change with pH value. Under soft acidity, these complexes exist in exchange equilibrium states. The equilibrium constant was calculated based on the ¹³C chemical shifts.

Key words: ¹³C NMR, Exchange equilibrium state, Platinum (Ⅱ) complex
