1-(3,5-Dimethyl­phen­yl)-2-(4-fluoro­phen­yl)-1H-phenanthro[9,10-d]imidazole

In the title compound, C₂₉H₂₁FN₂, the phenanthro tricyclic ring system is essentially planar with a maximum deviation of 0.030 (2) Å and makes dihedral angles between of 77.96 (6) and 37.18 (7)° with the dimethyl­phenyl and fluoro­phenyl rings, respectively. The crystal packing features weak C—H...π inter­actions involving the dimethyl­phenyl and other phenyl rings.

2-(4-Fluoro­phen­yl)-1-(4-meth­oxy­phen­yl)-1H-phenanthro[9,10-d]imidazole

In the title compound, C₂₈H₁₉FN₂O, the phenanthrene fused with an imidazole ring, constituting an essentially planar tetra­cyclic system [maximum deviation = 0.032 (2) Å], makes dihedral angles of 60.83 (4) and 80.55 (4)° with the fluoro­benzene and meth­oxy­benzene rings, respectively. The dihedral angle between the the meth­oxy­benzene and fluoro­benzene rings is 69.45 (6)°. In the crystal, C—H...O hydrogen bonds connect the mol­ecules into infinite strands along the b axis. The crystal structure is further consolidated by C—H...π inter­actions.
