Synthesis and crystal structure of a novel three-dimensional complex Ni(Iz)2(Bdc)(H2O)2 (Iz = imidazole, Bdc=1,4-benzenedicarboxylate)

A novel nickel(II) complex Ni(Iz)(2)(Bdc)(H2O)(2) (Iz = imidazole, Bdc = 1,4-benzenedicarboxylate) has been synthesized and structurally characterized by X-ray analysis. The crystal is of monoclinic, space group P2(1)/n with a = 5.5079(5), b = 15.0973, c = 9.9825(9) angstrom, beta = 90.2380(10)degrees, C14H16N4NiO6, M-r = 395.02, Z = 2, V = 830.08(13) angstrom(3), D-c = 1.580 g/cm(3), mu(MoK alpha) = 1.208 mm(-1), F(000) = 408, R = 0.0234 and wR = 0.0603 for 1379 observed reflections (I > 2 sigma(I)). In the title complex, adjacent nickel(II) ions are bridged through the oxygen atoms of carboxylic groups in syn-anti, conformation, yielding an infinite one-dimensional chain. These chains are linked to each other to form a 3-D network structure by three kinds of hydrogen-bonding interactions.
