Syntheses, Characterizations and Crystal Structures of Two Copper Coordination Polymers Both Having Cu2Cl2 Bridging Subunit [CuI(bipy)1/2Cl]n(1) and {[(CuII)4(phen)4(SSA)2Cl2](H2O)2(DMF)2}n(2)

Two copper coordination polymers [Cu-I(bipy)(1/2)Cl] (n) (1) and {[(Cu-II)(4)(phen)(4)(SSA)(2)Cl-2] (H2O)(2)(DMF)(2)} (n) (2)(bipy = 4,4'-bipyridine, phen = 1,10-phenanthroline, H(3)SSA = 5-sulfosalicylic acid, DMF = N,N-dimethylformamide) have been prepared and characterized by X-ray diffraction, elemental analysis, IR spectrum and 2 was also studied by cyclic voltammetric method. X-ray analysis indicates that both of them have Cu2Cl2 bridging subunit. Complex 1 is a two dimensional network structure. While 2 shows a one dimensional zigzag chain. Electrochemistry studies reveal that complex 2 undergo a quasi reversible one-electron metal-centered redox process at E (1/2) = +0.062 V.
