Abstract: In the title complex, [Zn(C10H7N2O2)2(H2O)], the ZnII ion and water O atom are located on a crystallographic twofold rotation axis and the metal atom assumes a distorted trigonal-bipyramidal ZnN4O coordination geometry. An intramolecular O-HO hydrogen bond occurs within the ligand and intermolecular O-HO hydrogen bonds involving the water molecule result in a sheet structure in the crystal structure. In addition, a short C-O contact between the O atom of the deprotonated hydroxyl group and a nearby pyridine ring [OCg = 3.977 (2) Å, where Cg is the centroid of the pyridine ring] is observed.
