The reaction of the chloride form of lithium aluminum layered double hydroxide (Li-Al LDH) with an aqueous solution of NaFeEdta · 2H2O (pH 3.7) was studied. Anion exchange of chloride ions for [FeEdta]− anions almost does not occur under the conditions of our experiment. Increasing pH to 8.0 initiates anion exchange of chloride ions for [Fe(OH)Edta...

Heats of reactions between a nickel(II) ion and β-alanine were measured calorimetrically at 288.15, 298.15, and 308.15 K and ionic strengths of 0.5, 1.0, and 1.5 (KNO3). Thermochemical data were processed with account for stepwise equilibria; attendant protolytic processes were taken into account together with complexing reactions. Extrapolation to...

Modeling of local defects with dangling bonds appearing in amorphous selenium on the destruction of the continuous random network (CRN) induced by photoexcitation was performed in the cluster approximation with inclusion of correlation effects at the second-order perturbation theory (MP2) level. It was shown that the interaction of moieties with da...

Phase formation in the Re-Se-Br-MBr systems (M = K, Rb, Cs) was studied by NMR spectroscopy and powder X-ray diffraction. The reactions taking place in alkali metal halide melts were found to give, among the series of cluster anions [{Re6Se8 − nBrn}Br6](4 − n)− (0 ≤ n≤ 4), polymeric complexes Re6Se8Br 2 and M2Re6Se8Br4 (M = Cs, Rb) and salts contai...

The heats of solution of tetrahexylammonium and tetraheptylammonium bromides in water were measured at 318.15 and 328.15 K. The standard enthalpies and specific heats of solution and the temperature changes in the free energy and entropy of solution were calculated. A comparison of the thermodynamic properties of solutions for the homologous series...
