2,4,5-Triphenyl-1-(prop-2-en-1-yl)-1H-imidazole

In the title compound, C(24)H(20)N(2), one of the ring C atoms and one of the ring N atoms are disordered over two sets of sites in a 0.615 (3):0.385 (3) ratio. The two parts of the disordered imidazole ring adopt an envelope conformation, with the undisordered ring N atom as the flap, displaced by −0.118 (6) and 0.226 (7) Å, respectively, in the two disorder components from the plane through the other ring atoms. The crystal structure features C—H⋯N hydrogen bonds and C—H⋯π inter­actions, which lead to the formation of infinite chains along [010].
