چکیده
The title compound, C(16)H(16)N(4)O(2), crystallizes with two mol-ecules in the asymmetric unit, which are related by a non-crystallographic centre of inversion. The phenyl-ene rings are twisted out of the mean plane of the triazole ring by 19.3 (1) and 21.4 (1)° for one independent mol-ecule and by 16.3 (1) and 18.1 (1)° for the other mol-ecule. In the crystal, adjacent mol-ecules are linked by amine-triazole N-H⋯N hydrogen bonds, forming chains running along the a axis.

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-dime...
