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.
