Abstract
In the title complex, [NiCl(2)(C(8)H(6)N(2)O)(2)(H(2)O)(2)], the Ni(II) ion is located on an inversion center and is six-coordinated by two N atoms of 1H-quinazolin-4-one ligands, two chloride ions and two water mol-ecules. The water mol-ecules are involved in intra- and inter-molecular O-H⋯O and O-H⋯Cl hydrogen bonding. Inter-molecular N-H⋯O and N-H⋯Cl hydrogen bonds are formed between ligands. In addition, weak π-π inter-actions are observed between the benzene rings of the ligands [centroid-centroid distance = 3.580 (3) Å]. The inter-molecular hydrogen bonds and π-π inter-actions lead to the formation of a three-dimensional supra-molecular network.
