Abstract
In the title complex, [NiCl2(C8H6N2O)2(H2O)2], the NiII 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 molecules. The water molecules are involved in intra- and intermolecular O—H⋯O and O—H⋯Cl hydrogen bonding. Intermolecular N—H⋯O and N—H⋯Cl hydrogen bonds are formed between ligands. In addition, weak π–π interactions are observed between the benzene rings of the ligands [centroid–centroid distance = 3.580 (3) Å]. The intermolecular hydrogen bonds and π–π interactions lead to the formation of a three-dimensional supramolecular network.
