2,2'-(4-Methyl-4H-1,2,4-triazole-3,5-di-yl)dibenzene-sulfonamide
Abstract:
In the title compound, C(15)H(15)N(5)O(4)S(2), the dihedral angles between the central 1,2,4-triazole ring and the pendant benzene rings are 55.61 (10) and 68.59 (10)°; the dihedral angle between the benzene rings is 63.66 (9)°. Intra-molecular N-H⋯N and N-H⋯O hydrogen bonds generate S(7) and S(12) rings, respectively. In the crystal, sheets extending in the (101) plane arise, with the mol-ecules linked by C-H⋯O, N-H⋯N and N-H⋯O inter-actions. A C-H⋯π inter-action further consolidates the structure.
