Abstract: The asymmetric unit of the title compound, C25H22N2O, contains two independent mol­ecules (A and B), with significantly different conformations. In mol­ecule 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 mol­ecule 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(H2)-C(H)-C(H2) torsion angles of the prop-1-ene group in the two mol­ecules are very similar, 0.5 (3) and 1.3 (4)° for mol­ecules A and B, respectively. The crystal structure is stabilized by C-H...[pi] inter­actions.
