The title compound, C25H20N2O2, crystallized with two molecules in the asymmetric unit, in one of which the atoms of the terminal propenyl group are disordered over two sets of sites, with a refined occupancy ratio of 0.870 (4): 0.130 (4). The central imidazole ring makes dihedral angles of 25.51 (11), 40.73 (11) and 27.36 (11)degrees with the three pendant rings in one molecule and 22.56 (10), 60.72 (10) and 5.85 (10)degrees in the other. In the crystal, molecules are linked by N-H center dot center dot center dot N and CH center dot center dot center dot O hydrogen bonds, forming a three-dimensional network. The crystal structure also features C-H center dot center dot center dot pi interactions and pi-pi stacking [centroid-centroid distances = 3.8834 (18) and 3.9621 (17) angstrom] interactions.
