5,5′-Di-4-pyridyl-2,2′-(p-phenylene)di-1,3,4-oxadiazole

Abstract

In the crystal structure of the title compound, C20H12N6O2, the molecules are located on centres of inversion. The complete molecule is almost planar, with a maximum deviation from the mean plane of 0.0657 (1) Å for the O atom. In the crystal, molecules are stacked into columns elongated in the a axis direction. The centroid–centroid distances between the aromatic rings of the molecules within the columns are 3.6406 (1) and 3.6287 (2) Å. Molecules are additionally connected via weak intermolecular C—H...N hydrogen bonding.
