The asymmetric unit of the title compound, C(25)H(22)N(2)O, contains two independent mol-ecules (A and B), with significantly different conformations. In mol-ecule A, the central imidazole ring makes dihedral angles of 88.26 (10) and 12.74 (11)° with the two phenyl rings, and 22.06 (9)° with the benzene ring. In mol-ecule B, one of the phenyl rings is disordered over two sites, each having an occupancy of 0.5. Here the central imidazole ring forms dihedral angles of 79.24 (10)° with the ordered phenyl ring, and 3.5 (5) and 22.6 (5)° with the two parts of the disordered phenyl ring. The dihedral angle involving the benzene ring is 67.49 (10)°. The -N-C(H(2))-C(H)-C(H(2)) torsion angles of the prop-1-ene group in the two mol-ecules are very similar, 0.5 (3) and 1.3 (4)° for mol-ecules A and B, respectively. The crystal structure is stabilized by C-H⋯π inter-actions.
