In the crystal structure of the mononuclear title complex, [Ni(C10H9N2O2)2(H2O)], the NiII ion is five-coordinated in a distorted square-pyramidal geometry by two N atoms and two O atoms from 2,3-dimethyl-4-oxopyrido[1,2-a]pyrimidin-9-olate ligands and one O atom from a water molecule. O-HO hydrogen bonds between the coordinated water molecule and the ligand connect adjacent molecules, forming a ribbon parallel to the b axis.
