Abstract: 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-HO 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 - interactions also occur [shortest centroid-centroid distance = 3.684 (3) Å].
