Interaction between ligands in ternary complexes of cadmium(II) with phenanthroline and phenylalkylmalonates in solution

All Rights Reserved. Interaction between ligands in ternary complexes of cadmium(II) with phenanthroline and phenylalkylmalonates in solution. Guan, W.; Ge, C. H.; Zhang, X. D.; Tong, J.; Liu, Q. T. (Department of Environmental Science, Liaoning University, Shenyang 110036, Peop. Rep. China). Russian Journal of Coordination Chemistry, 32(11), 811-814 (English) 2006 Pleiades Publishing, Inc. CODEN: RJCCEY. ISSN: 1070-3284. DOCUMENT TYPE: Journal CA Section: 68 (Phase Equilibriums, Chemical Equilibriums, and Solutions) Section cross-reference(s): 72, 77 The formation and stability of the ternary complexes of cadmium(II) with phenanthroline and malonate, phenylmalonate, benzylmalonate, 2-phenylethylmalonate, and 3-phenylpropylmalonate are studied by the potentiometric pH-titrn. technique in 40 % (vol./vol.) dioxane-water at 25 °C and 0.1 mol/l ionic strength (NaNO3). In all systems, there are stable ternary complexes. The complexes possess enhanced stability relative to their statistical values. The possible reasons that lead to these results are discussed in terms of p-electron back donation from metal ions to ligands and the intramol. ligand-ligand arom. ring stacking interaction. 1H NMR measurements are used to demonstrate the arom. ring-stacking interaction. 2613-89-0 and 616-75-1 which are cas registry numbers of substances are two of reagents here. The relative contribution of each interactions to the enhanced stability is also estd. The results show that there are two weak interactions simultaneously obsd. in these ternary complexes. The interaction strength of arom. ring stacking in the ternary complexes increases in the phenylalkylmalonate ligand order: L0 < L1 < L2 u L3 (L0 = phenylmalonate, L1 = benzylmalonate, L2 = 2-phenylethylmalonate, L3 = 3-phenylpropylmalonate). .
