Hydrothermal synthesis, crystal structure and electrochemical properties of complex [Cd(phen)3]•(ClO4)2 •(p-MBA)2•(H2O)2

One new cadmium complex [Cd(phen)(3)]-(ClO4)(2)(p-MBA)(2)-(H2O)(2) has been hydrothermally synthesized by reacting p-methylbenzoic acid (p-MBA), 1, 10-phenanthroline (phen) and cadmium perchlorate. It crystallizes in the triclinic system, space group P-(1) over bar, with a = 1.2809(3), b = 1.3431(3), c = 1.3734(3) nm, alpha = 84.259(4), beta = 71.603(3), gamma = 74.424(3)degrees, V= 2.1594(8) nm(3), D-c = 1.532 g/cm(3), Z = 2, F(000) = 1008, mu = 0.697 mm(-1), R = 0.0646 and wR = 0.1648. The crystal structure shows that the cadmium. ion is coordinated with six nitrogen atoms from three 1,10-phenanthroline molecules, forming a distorted octahedral coordination geometry. The result of electrochemical property analysis shows that the electron transfer in the electrode reaction is irreversible.
