In the title compound, CHNO·CHOS, the [1,2,4]triazolo[1,5-]pyridine ring system is almost planar and makes dihedral angles of 16.33 (7) and 46.80 (7)°, respectively, with the phenyl-amino and phenyl rings. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds into chains along the axis direction through the dimethyl sulfoxide solvent mol-ecule, forming (10) (6) motifs. These chains are connected S-O⋯π inter-actions, π-π stacking inter-actions between the pyridine rings [centroid-to-centroid distance = 3.6662 (9) Å] and van der Waals inter-actions. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (28.1%), C⋯H/H⋯C (27.2%), N⋯H/H⋯N (19.4%) and O⋯H/H⋯O (9.8%) inter-actions.
在标题化合物CHNO·CHOS中，[1,2,4]三唑并[1,5 - ]吡啶环系几乎呈平面状，分别与苯氨基环和苯环形成16.33 (7)°和46.80 (7)°的二面角。在晶体中，分子通过分子间的N - H⋯O和C - H⋯O氢键沿着轴方向通过二甲基亚砜溶剂分子连接成链，形成(10) (6) motif。这些链通过S - O⋯π相互作用、吡啶环之间的π - π堆积相互作用[质心到质心距离 = 3.6662 (9) Å]和范德华相互作用相连。晶体结构的 Hirshfeld 表面分析表明，对晶体堆积最重要的贡献来自H⋯H (28.1%)、C⋯H/H⋯C (27.2%)、N⋯H/H⋯N (19.4%)和O⋯H/H⋯O (9.8%)相互作用。
