Abstract

The triazole ring in the title compound, C(14)H(12)N(4)O(2)·H(2)O, makes dihedral angles of 36.9 (1) and 37.3 (1)° with the two benzene rings. Each hy-droxy group is a hydrogen-bond donor to a two-coordinate N atom of an adjacent mol-ecule; these O-H⋯N hydrogen bonds generate a layer parallel to the ab plane. Adjacent layers are linked by N--H⋯O and O(water)-H⋯O hydrogen bonds into a three-dimensional network.
