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 methylene group, forming a dihedral angle of 81.87 (15)°. In the crystal, molecules are linked into chains along [001] by O—H
O hydrogen bonds. The chains are consolidated into a three-dimensional architecture by C—HO, C—Hπ and π–π [centroid–centroid distance between the five- and six-membered rings of the benzotriazole ring system = 3.595 (3) Å] interactions.

In the title compound, C18H15BrClNO2, the indole ring system forms a dihedral angle of 86.9 (2)° with the 3-chlorobenzyl ring. In the crystal, molecules form inversion dimers connected via pairs of O—HO hydrogen bonds.

The asymmetric unit of the title compound, C16H11BrN2O, contains two independent molecules with slightly different geometries. The 4-bromobenzene ring forms dihedral angles of 26.0 (2) and 39.9 (7)° with the pyrazole ring in the two molecules while the phenyl ring is oriented at 19.7 (5) and 7.3 (0)° with respect to the pyrazole ring.
