Özet

In the title compound, C20H12N6O·C2H6OS, the [1,2,4]triazolo[1,5-a]pyridine ring system is almost planar and makes dihedral angles of 16.33 14;(7) and 46.80 14;(7)°, respectively, with the phenylamino and phenyl rings. In the crystal, molecules are linked by intermolecular N - H⋯O and C - H⋯O hydrogen bonds into chains along the b-axis direction through the dimethyl sulfoxide solvent molecule, forming C(10)R 21(6) motifs. These chains are connected via S - O⋯π interactions, π-π stacking interactions between the pyridine rings [centroid-to-centroid distance = 3.6662 14;(9) 14;Å] and van der Waals interactions. 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%) interactions.
