title: 1,3-Dimethyl-5-methyl-sulfonyl-1H-pyrazolo-[4,3-e][1,2,4]triazine.
abstract: In the title compound, C(7)H(9)N(5)O(2)S, the pyrazolo-[4,3-e][1,2,4]triazine fused-ring system is essentially planar [maximum deviation = 0.0420 (3) Å]. In the crystal, mol-ecules related by twofold axes are linked into a mol-ecular net via inter-molecular C-H⋯O and C-H⋯N hydrogen bonds. π-π inter-actions are observed between the triazine and pyrazole rings of mol-ecules related by the the twofold axis and inversion symmetry with centroid-centroid distances of 3.778 (3) and 3.416 (3) Å, respectively.
