In the title compound, C18H17N3O·0.5C2H5OH, the dihedral angles between the central imidazole rings and the pendant benzene rings are 42.06 (15) and 2.01 (16)° in one asymmetric molecule and 47.91 (15) and 7.31 (14)° in the other. An intramolecular N—H
O hydrogen bond occurs in each imidazole molecule. In the crystal, the components are connected by O—HN, N—HO, C—HO and N—HN hydrogen bonds. Weak aromatic π–π interactions also occur [shortest centroid–centroid distance = 3.684 (3) Å].

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—Hπ and π–π interactions [centroid–centroid separation = 3.695 (4) Å].

The asymmetric unit of the title compound, C23H21N3, consists of two symmetry-independent and conformationally different molecules [the comparable dihedral angles between the imidazole ring and the three benzene rings being 38.5 (2)/61.5 (3)/3.37 (17) and 45.8 (2)/36.01 (19)/46.94 (17)°]. In the crystal, intermolecular imidazole N—HN hydrogen-bonding interactions give a one-dimensional chain extending along [101].
