Crystal structure of 1-[2-(4-nitro­phen­yl)-4,5-diphenyl-1H-imidazol-1-yl]propan-2-ol

The title compound, C(24)H(21)N(3)O(3), crystallizes with two unique but closely r.m.s. overlay fit = 0.215 Å) comparable mol­ecules (1 and 2) in the asymmetric unit of the triclinic unit cell. In molecule 1, the dihedral angles between the central imidazlole ring and the benzene-ring substituents are 42.51 (9), 45.41 (9) and 56.92 (8)°, respectively. Comparable data for molecule 2 are 39.36 (10), 34.45 (11) and 60.34 (8)°, respectively. The rings at the 2-positions carry p-nitro substituents that subtend dihedral angles of 12.9 (4)° in mol­ecule 1 and 11.7 (4)° in mol­ecule 2 to their respective benzene ring planes. The imidazole rings also have propan-2-ol substituents on the 1-N atoms, which adopt extended conformations for the N—C—C—C chains. In the crystal, classical O—H⋯N hydrogen bonds combine with C—H⋯O, C—H⋯N and C—H⋯π(ring) hydrogen bonds and stack the molecules along the a-axis direction.
