The influence of the conditions and the method of synthesis on the composition of copper(II) complexes with galactaric acid (H2Gala) has been studied. In aqueous and water-DMSO solutions, 1 : 1 complexes are formed. Depending on the procedure and conditions of the synthesis, CuGala · 4H2O, Cu(HGala)2 · 4H2O, and (CuOH)2Gala · 2H2O compounds have been obtained. The structure of the coordination environment of the metal ion has been identified by IR spectroscopy. 相似文献

Effect of anode amalgamation on the degree of passivation of the electrodes and on the current efficiency in electrosynthesis of coordination compounds of copper(II), nickel(II), zinc(II), and cadmium(II) with galactaric acid was studied. An improvement of anodic synthesis characteristics was observed when amalgamated zinc, copper, and cadmium were used. Complex compounds of 1 : 1 composition were obtained and the structure of the coordination environment of the metal ion was determined by IR spectroscopy. 相似文献

Complex formation by galacturonic acid with copper(II) ion in water solution is studied by themethods of EPR spectroscopy. At the pH > 3 the EPR signal (g 2.174) confirms the complex formation at theligand carboxylic group. The following complex formation parameters are measured: equilibrium constant'g factor, hyperfine coupling constant, average complex lifetime. From the data of electron spectra invisible region the complex composition and stability constant is defined for copper(II) and neodymium(III). 相似文献
