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.
