Abstrakt: A nickel(II) terephthalate complex, viz. [Ni(C 6 H 4 N 2 ) 2 (H 2 O) 4 ](O 2 CC 6 H 4 CO 2 )·4H 2 O, 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(H 2 O) 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 π-π stacked pyridine-3-carbo-nitrile rings and C-H⋯O inter-actions.
