Synthesis, crystal structure and Hirshfeld surface analysis of 3,3'-[ethane-1,2-diylbis(sulfanedi-yl)]bis-(1H-1,2,4-triazol-5-amine).

The title compound, C6H10N8S2, crystallizes in the monoclinic crystal system with P21/c space group. The mol-ecular geometry features a flexible ethyl-enedi-thio spacer inducing a 76.69 (11)° dihedral angle between triazole moieties; this twist precludes π-π stacking. The crystal cohesion is instead driven by a two-dimensional supra-molecular framework maintained by strong N-H⋯N hydrogen bonds and auxiliary N⋯S and C⋯S contacts. Qu-anti-tative Hirshfeld surface analysis confirms the dominance of hydrogen-involving inter-actions (98.8%), with N⋯H (40.4%) and H⋯H (27.1%) as the primary contributors to the packing arrangement.
