In the title compound, C16H15N3O2·H2O, the two benzene rings and the triazole ring lie almost in the same plane, the triazole ring forming dihedral angles of 5.07 (9) and 5.80 (8)° with the benzene rings. In the crystal, there are three relatively strong intermolecular O—H...N and N—H...O hydrogen bonds, which lead to the formation of a one-dimensional double chain running parallel to theaaxis. Weak π—π interactions between the benzene rings of neighboring chains with a centroid–centroid distance of 3.893 (4) Å result in the formation of layers parallel to theacplane.

In the title compound, C27H29BrN4O, benzimidazole ring system and the amide moiety are planar [r.m.s. deviations = 0.016 (2) and 0.017 (1) Å, respectively]. The molecule adopts a conformation in which the amide linkage is almost perpendicular to the central ring [dihedral angle = 85.79 (8)°], while the benzimidazole ring system makes a dihedral angle of 70.26 (11)° with the central ring. In the crystal, the molecules form dimers through N—H...O hydrogen bonds and C—H...O interactions. These dimers are further linked into zigzag ribbons along [201] by weak C—H...Br interactions. As a result of the bulky nature of the molecule, as evidenced by the large dihedral angles between rings, there is little evidence for any π–π interactions.
