Synthesis and Crystal Structure of a New Chain Coordination Polymer [Cu(inio)2(H2O)]∞(Inio = Isonicotinic Acid N-Oxide)

A new Cu(Ⅱ) coordination polymer [Cu(inio)2(H2O)]( (inio = isonicotinic acid N-oxide) with chemical formula C12H10CuN2O7 was prepared and its crystal structure has been determined by X-ray analysis. The complex crystallizes in the monoclinic system, space group C2/c with a = 12.455(3), b = 6.202(1), c = 16.555(3) (A。), β = 106.776(3)(A。), V = 1224.3(4) (A。)3, Z = 4, Mr = 357.76, Dc =1.941 g/cm3,μ(MoKα) = 1.827 mm－1, F(000) = 724, R = 0.0601 and wR = 0.1417 for 908 observed reflections (I > 2σ(I)). The Cu(Ⅱ) atom is coordinated by an elongated square pyramid geometry. The deprotonated isonicotinic acid N-oxides form a double-bridge between each pair of Cu(Ⅱ) ions in trans form through two oxygen atoms from the carboxyl groups and two other oxygen atoms from the -NO groups, respectively, which leads to an infinite one dimensional chain. The two adjacent elongated Cu(Ⅱ) square pyramidal geometries are arranged in trans form in the same chain. The O-H…O hydrogen bonds extend the chain structure into two-dimensional layers.
