| Popis: | 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 (7) and 46.80 (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)R21(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 (9) 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. |
