1-(4-Meth­oxy­phen­yl)-2-[4-(tri­fluoro­meth­yl)phen­yl]-1H-phenanthro[9,10-d]imidazole

In the title compound, C(29)H(19)F(3)N(2)O, a phenanthroline-fused imidazole tetra­cyclic system, the fused benzene rings deviate slightly from the central ring and make dihedral angles with this ring of 3.47 (8) and 3.05 (8)°. The tri­fluoro­methyl­phenyl ring is roughly coplanar with the phenanthroline-fused imidazole tetra­cyclic system [dihedral angle = 11.02 (6)°], while the meth­oxy­phenyl ring is almost perpendicular [dihedral angle = 87.65 (6)°]. There are intra­molecular C—H ⋯π inter­actions involving the meth­oxy­phenyl ring and the central phenanthroline ring, as well as an inter­molecular C—H⋯π inter­action involving the phenanthroline ring. In addition, there is an inter­molecular π–π inter­action involving the central phenanthroline ring and the tri­fluoro­methyl­phenyl ring [centroid–centroid distance = 3.685 (2) Å], as well as C—H⋯N inter­actions linking the mol­ecules into dimers.
