4-{3-[Hydr-oxy(phen-yl)meth-yl]-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-4-yl}benzene-sulfonamide

Abstract

In the title compound, C(15)H(14)N(4)O(3)S(2), the hydr-oxy group is disordered over two positions with occupancies of 0.619 (5) and 0.381 (5). The benzene ring attached to the heterocycle makes a dihedral angle of 86.92 (9)° with respect to the best plane through the five-membered ring. The crystal packing is stabilized by inter-molecular O-H⋯O, N-H⋯S, N-H⋯N, C-H⋯O and C-H⋯N hydrogen bonds, and N-H⋯π and C-H⋯π inter-actions.
