Hydrothermal synthesis, crystal structure and electrochemical properties of complex {CdI(phen)(H2O)[C8H11O2(COO)]}I•H2O

One Complex {CdI(phen) (H2O)[C8H11O2(COO)]}center dot H2O with bicycle [2.2.1]hept-2-en-5,6-dicarboxylic acid [C7H8(COOH)(2)], hydriodic acid and 1,10-phenanthroline (phen) has been synthesized by means of hydrothermal way and characterized. It crystallizes in the triclinic space group P1, with a=0.975 4(2) nm, b =0.990 0(2) nm, c = 1.319 1(3) nm, alpha=89.146(4)degrees, ss=69.800(3)degrees, gamma=68.718(3)degrees, V= 1. 105 0(4) nm(3), D-c=1.914 g center dot cm(-3), Z=2, F(000)=620, Final R-1=0.033 2, wR(2)=0.085 7, GooF=1.092. The crystal structure shows that the cadmium ion is coordinated with two oxygen atoms from one C7H10(COOH)(2) molecule, two nitrogen atoms from the 1,10-phenanthroline, one oxygen atom from one water molecule and one iodine ion, respectively, forming a distorted octahedral coordination geometry. The cyclic voltametric behavior of the complex is also reported.
