| Summary: | The title compound, C24H20N6O2, is a novel 1,3,4-oxadiazole derivative which has potential as an electron-transporting material in organic electroluminescent (EL) devices. In the crystal, the molecular framework is almost planar with an r.m.s. deviation of 0.091 (4) Å and it exists in an E form. Intramolecular C—H...O and C—H...N hydrogen bonds are observed between the benzene and 1,3,4-oxadiazole rings. The tert-butyl group is disordered over two sites, with occupancy factors of 0.78 (1) and 0.22 (1) for the major and minor orientations, respectively. In the crystal structure, molecules aggregate via C—H...N interactions, forming molecular tapes along the b axis, which aggregate to form a molecular sheet via C—H...N interactions.
