  Interaction of K2PdCl4 with aminoalkyldiphosphonic acids

  摘要：

  Complexing of K2PdCl4 with 3-amino-1-hydroxypropylidene-1,1-diphosphonic acid (AHPDP) and 1-aminoethylidene-1,1-diphosphonic acid (AEDP) was studied by pH titration, spectrophotometry, and P-31 NMR spectroscopy using metal to ligand mole ratios of 1 : 1 and 1 : 2. In equimolar complexes, AHPDP is coordinated to palladium(II) via two phosphonic oxygen atoms, whereas AEDP is coordinated via the amino nitrogen atom and a phosphonic oxygen atom. In the bisligand palladium(II) complex with AEDP, both ligand molecules are coordinated in a bidentate mode by the amino nitrogen atom and a phosphonic oxygen atom.

  Complexation in the systems K2PdCl4-3-amino-1-hydroxypropane-1,1-diyldiphosphonic acid (AHPDP) and K2PdCl4-1-aminoethane-1,1-diyldiphosphonic acid (AEDP) was studied using pH-potentiometry, spectrophotometry, and P-31 NMR spectroscopy. It was found that AHPDP in equimolar complexes is coordinated by Pd(II) in a bidentate fashion through two phosphonate O atoms forming a six-membered chelate [O,O]-ring, while AEDP is coordinated through the N atom and one phosphonate O atom forming a five-membered chelate [N,O]-ring. In 1: 2 complexes of Pd(II) with AEDP, the second AEDP molecule is coordinated by Pd(II) in a similar way to form a second five-membered [N,O]-ring. The latter complexes show cis-trans and syn-anti isomerism. The structural characteristics of the corresponding isomers were calculated at the DFT level of theory and their stabilities were compared.
