摘要:
Complex formation in a K2PdCl4-HEDP system (HEDP is 1-hydroxyethylidene-1,1-diphosphonic acid) at the metal-to-ligand ratios 1 : 1 and 1 : 2 is studied by P-31 and H-1 NMR spectroscopy. The formation of equimolar complexes, in which HEDP is coordinated to palladium(II) in a bidentate mode through two oxygen atoms of the phosphonic groups, is found in these systems. The structure and charge characteristics of conformers of the complexes are simulated by the quantum-chemical methods.
