Tetra-aqua-bis-(pyridine-3-carbo-nitrile-?N 1)nickel(II) benzene-1,4-di-carboxyl-ate tetra-hydrate.

ABSTRACT: A nickel(II) terephthalate complex, viz. [Ni(C6H4N2)2(H2O)4](O2CC6H4CO2)·4H2O, has been synthesized and studied by single-crystal X-ray diffraction. It crystallizes in the triclinic space group P . The crystal structure shows an approximately octa-hedral coordination environment of the complex with the [Ni(H2O)4(3-NCpy)2]2+ (3-NCpy is pyridine-3-carbo-nitrile) cation associated with four free water mol-ecules and hydrogen bonded to a terephthalate dianion [graph set R 2 2(8)]. The supra-molecular structure of the compound is stabilized by a three-dimensional array of O-H?O and O-H?N hydrogen bonds, along with ?-? stacked pyridine-3-carbo-nitrile rings and C-H?O inter-actions.
