  摘要：

  Ultrasonic absorption of aqueous cadmium(II) acetate, propionate, and n-butyrates has been measured with a pulse technique over the frequency range 3-260 MHz. The single relaxations observed in the metal-rich concentration regions are attributed to the complex formation of cadmium(II) carboxylates via the Eigen-Tamm mechanism of stepwise association. The reaction parameters are determined from the concentratio dependences of the relaxation frequency and amplitude. The association constant for outer-sphere complexing and the rate constant for ligand substitution lie in the ranges 0.91-1.14 and (4.1-5.4) x 10(8) s-1, respectively, both being almost independent of the nature of the carboxylate ions, in contrast to the case of zinc(II) carboxylates previously reported. The volume changes of the outer-sphere complexing and those of the ligand substitution are determined to be 1.7-2.4 and 4.6-6.7 cm3 mol-1, respectively; these values are very different from those of cadmium(II) thiocyanate reported earlier.

  Cadmium carboxylates and their coordination complexes are synthesized by using an electrochemical technique in the presence of different carboxylic acids (RCOOH) using cadmium and a platinum as the anode and cathode respectively and tetrabutyl ammonium chloride as a supporting electrolyte. The electrochemical oxidation of anodic cadmium in acetonitrile solution with different carboxylic acids or with 1,10-phenanthroline (phen) and 2,2’-bipyridyl (bipy) yield the complexes Cd(OOCR)2 and Cd(OOCR)2L (L = phen or bipy), respectively. The results from spectroscopic studies FTIR, elemental analysis and physical measurements confirm the existence of bonding between the carboxylate groups of different carboxylic acids with cadmium. Current efficiencies of all these synthesized compounds are also discussed.

  Ultrasonic absorption of aqueous cadmium(II) acetate, propionate, and n-butyrates has been measured with a pulse technique over the frequency range 3-260 MHz. The single relaxations observed in the metal-rich concentration regions are attributed to the complex formation of cadmium(II) carboxylates via the Eigen-Tamm mechanism of stepwise association. The reaction parameters are determined from the concentratio dependences of the relaxation frequency and amplitude.
