Structure of Palladium(II) Complexes with Nitrilotrimethylenephosphonic Acid in Aqueous Solutions According to ~(31)P and ~1H NMR Data

摘要

The complex formation in the K2PdCl4-nitrilotrimethylenephosphonic acid (NTMP) system with a metal to ligand molar ratio of 1 : 1 and 1 : 2 was studied by ~(31)P and ~1H NMR spectroscopy. The formation of equimolar complexes with NTMP coordinated in the bidentate ([N,O]) and tridentate ([N,O,O]) fashions depending on the reactant and chloride ion concentrations and solution pH was observed.
