2,5-Bis(3,4-dimethoxyphenyl)-1,3,4-oxadiazole

Abstract

In the title compound, C18H18N2O5, which was synthesized by reacting N,N′-bis-(3,4-dimethoxybenzoyl)hydrazine with POCl3, the dihedral angles between the central oxadiazole ring and pendant 3,4-dimethoxyphenyl rings are 11.37 (7) and 3.09 (7)°. In the crystal, weak C—H...O and π–π [shortest centroid–centroid separation = 3.7370 (11) Å] interactions are present, giving rise to a layered packing motif.
