title: 1-Benzyl-1H-benzotriazole 3-oxide monohydrate.
abstract: In the title hydrate, C13H11N3O·H2O, the benzotriazole ring system is planar (r.m.s. deviation = 0.007 Å) and is almost orthogonal to the phenyl ring to which it is linked by a methyl-ene group, forming a dihedral angle of 81.87 (15)°. In the crystal, mol-ecules are linked into chains along [001] by O-H⋯O hydrogen bonds. The chains are consolidated into a three-dimensional architecture by C-H⋯O, C-H⋯π and π-π [centroid-centroid distance between the five- and six-membered rings of the benzotriazole ring system = 3.595 (3) Å] inter-actions.
