Abstract: In the title compound, C28H18N2O5, the dihedral angle between the terminal benzoate rings is 20.67 (12)°. The central oxadiazole ring is almost coplanar with its two benzene ring substituents, making dihedral angles of 4.80 (16) and 5.82 (16)°. In the crystal, pairs of C-HO hydrogen bonds form inversion dimers with R22(40) ring motifs. The structure also features C-HO, C-H and - interactions [centroid-centroid separation = 3.695 (4) Å].
