4-[5-(4-Benzoyl­oxyphen­yl)-1,2,4-oxa­diazol-3-yl]phenyl benzoate

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—H...O hydrogen bonds form inversion dimers with R₂²(40) ring motifs. The structure also features C—H...O, C—H...π and π–π inter­actions [centroid–centroid separation = 3.695 (4) Å].

3-Methyl-1,5-diphenyl-4,5-dihydro-1H-pyrazole

In the title compound, C₁₆H₁₆N₂, the dihydro­pyrazole ring adopts a shallow envelope conformation, with the C atom bearing the phenyl group displaced by 0.298 (2) Å from the other atoms (r.m.s. deviation = 0.015 Å). The dihedral angles between the four near coplanar atoms of the central ring and the N- and C-bonded phenyl groups are 13.49 (13) and 82.22 (16)°, respectively.
