In the title benzohydrazide hydrate, C14H12N2O3·H2O, the dihedral angle between the aromatic rings is 58.11 (6)° and the C=O and N—H groups adopt an anti orientation. The main twist in the molecule occurs about the C(=O)—Car (ar = aromatic) bond, with an N—C(=O)—Car—Car torsion angle of −43.5 (2)°. In the crystal, the components are linked by N—H
O, O—HN and O—HO hydrogen bonds. These interactions generate [10-1] chains, with adjacent organic molecules linked by inversion symmetry generating either pairs of N—HO links [R22(16) loops] or pairs of O—HO links [R22(20) loops]. Pairs of water molecules are located in the R22(20) loops and form their own O—HO and O—HN hydrogen bonds to adjacent organic molecules in the chain. Finally, an interchain O—HO hydrogen-bond link from the 4-hydroxy group generates (010) sheets.
