title: N-Phenyl-N-{4-[5-(4-pyrid-yl)-1,3,4-oxadiazol-2-yl]phen-yl}aniline.
abstract: The title compound, C(25)H(18)N(4)O, is a non-planar bipolar ligand containing triphenyl-amine and 1,3,4-oxadiazole units. In the mol-ecule, the benzene ring, the 1,3,4-oxadiazole ring, and the pyridine ring are twisted slightly with respect to each other [dihedral angle between the benzene and 1,3,4-oxadiazole rings = 9.4 (4) and between the 1,3,4-oxadiazole and pyridine rings = 3.0 (4)°]. Moreover, the dihedral angles between the two phenyl rings and the benzene ring are 88.2 (4) and 113.3 (4)°, and that between the two phenyl rings is 67.9 (4)°. The closest distances between the pyridine ring and the 1,3,4-oxadiazole and benzene rings in adjacent mol-ecules are 3.316 and 3.363 Å, respectively, indicating the existence of π-π inter-actions.
