title: 2,2'-(4-Amino-4H-1,2,4-triazole-3,5-di-yl)diphenol.
abstract: The structure of the title compound, C(14)H(12)N(4)O(2), was determined as part of a project on the coordination chemistry of 1,2,4-triazole derivatives. In the crystal structure, one of the two benzene rings is almost coplanar with the five-membered triazole ring (mean deviation = 0.019 Å), whereas the second benzene ring is rotated by 51.973 (2)°. The two N-C-N-N torsion angles [170.365 (2) and -170.942 (3)°] indicate that the amido group is slightly twisted away from the triazole plane. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal structure, inter-molecular N-H⋯O and O-H⋯N hydrogen bonding is found.
