In the mol-ecular structure of the title compound, CHNO·HO, the angle between the triazole and arene rings is 87.39 (5)°. The water of crystallization connects the mol-ecules in the crystal packing. The crystal structure exhibits N-H⋯O, O-H⋯O and O-H⋯N inter-actions, resulting in the formation of a three-dimensional framework. The inter-molecular inter-actions were identified and qu-anti-fied using Hirshfeld surface analysis.
