Synthesis, crystal structure and Hirshfeld surface analysis of 3,3′-[ethane-1,2-diylbis(sulfanediyl)]bis(1 <i>H</i> -1,2,4-triazol-5-amine)

<jats:p> The title compound, C <jats:sub>6</jats:sub> H <jats:sub>10</jats:sub> N <jats:sub>8</jats:sub> S <jats:sub>2</jats:sub> , crystallizes in the monoclinic crystal system with <jats:italic>P</jats:italic> 2 <jats:sub>1</jats:sub> / <jats:italic>c</jats:italic> space group. The molecular geometry features a flexible ethylenedithio 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 supramolecular framework maintained by strong N—H...N hydrogen bonds and auxiliary N...S and C...S contacts. Quantitative Hirshfeld surface analysis confirms the dominance of hydrogen-involving interactions (98.8%), with N...H (40.4%) and H...H (27.1%) as the primary contributors to the packing arrangement. </jats:p>
