چکیده
In the title compound, C(8)H(6)N(4)O(2)S, the 1,2,4-triazole ring and the nitro group form dihedral angles of 6.26 (13) and 9.5 (3)°, respectively, with the phenyl ring. In the crystal, the mol-ecules are linked via pairs of N-H⋯S hydrogen bonds, generating [010] chains which contain R(2) (2) (8) ring motifs. The crystal structure is further stabilized by π-π stacking [centroid-centroid distance = 3.5491 (14) Å] inter-actions.
