1. N-Phenyl-N-{4-[5-(4-pyrid-yl)-1,3,4-oxadiazol-2-yl]phen-yl}aniline
Li-Ping Han, Bin Li, Jie Liu Acta Crystallogr Sect E Struct Rep Online. 2007 Dec 12;64(Pt 1):o242. doi: 10.1107/S1600536807065245.
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.

In the title compound, C(38)H(36)F(2)N(4)O(4), the pyrazole rings form dihedral angles of 50.02 (4) and 18.05 (4)° with their attached fluorobenzene rings, and make dihedral angles of 76.08 (4) and 73.54 (5)° with the aromatic ring of the attached phen-oxy group. In the crystal, the molecules are connected by weak C-H⋯π inter-actions.
