The secondary structure of the title compound, C₈H₇N₃O, consists of O-H...N hydrogen-bonding catemers, similar to those of the parent 1,2,4-triazole, where the molecules are linked by N-H...N bonds. Chains related by translation are linked by C-H(triazole)...O/N interactions to give a tertiary structure of corrugated sheets parallel to the ac plane. The quaternary structure is due to C-H(Ph)...O contacts and to the stacking of triazole rings from centrosymmetrically related sheets.
