2-(4-Fluoro-phen-yl)-1-(4-methyl-phen-yl)-1H-phenanthro[9,10-d]imidazole.

The phenanthrene tricyclic ring system in the title mol-ecule, C(28)H(19)FN(2), is slightly skewed with a dihedral angle of 7.50†(6)° between the outer benzene rings. The p-tolyl and fluoro-benzene rings are twisted from the attached imidazole ring by 70.40†(7) and 28.33†(7)°, respectively. In the crystal, C-H⋯F hydrogen bonds link the mol-ecules into zigzag chains in [001], and weak C-H⋯π inter-actions further consolidate the crystal packing.
