Crystal data for this complex： monoclinic, space group P21/c, a = 1.1481（3）, b = 1.1230（2）, c = 1.1759（3） nm, β = 97.054（4）^o, V= 1.5046（6） nm^3, Mr= 617.50, Dc = 1.363 g/cm^3, Z = 2, ,u（MoKa） = 0.627 mm^-1, F（000） = 646, S = 1.062, R 0.0443 and wR = 0.1178. The crystal structure shows that two neighboring cobalt（ID ions are linked together by one 4,4＇-bipy, and the whole complex molecule adopts a one-dimensional chain structure. Each cobalt（H） ion is coordinated with two nitrogen atoms from two 4,4＇-bipy molecules and four oxygen atoms from four water molecules, giving a distorted octahedral coordination geometry. The electrochemical properties were analyzed by combining with the crystal structure.展开更多
