2-Phenyl-5-(p-tolyl)-1,3,4-oxadiazole

چکیده
The title compound, C(15)H(12)N(2)O, adopts the expected near-planar geometry, the phenyl and tolyl rings being inclined relative to the oxadiazole ring by 3.8 (3) and 8.3 (2)°, respectively. This allows adjacent mol-ecules to pack in a parallel fashion and form stacking along [010] via π-π inter-actions [centroid-centroid distances = 3.629 (2) and 3.723 (2) Å]. Further inter-molecular inter-actions include C-H⋯π inter-actions and weak C-H⋯N hydrogen bonds, giving rise to a crossed herringbone packing motif.
