N,N-Di­phenyl-4-(1H-pyrrolo[1,2-f][1,10]phenanthro­lin-2-yl)­aniline ethanol monosolvate

The title compound, C₃₂H₂₁N₄·C₂H₅OH, crystallized as an ethanol monosolvate. In the mol­ecule of this phenanthroline derivative, the pyridine rings are almost coplanar, making a dihedral angle of 1.54 (13)°. The tri­phenyl­amine group, introduced as an electron donor, shows a propeller-type structure, and the dihedral angles between the benzene rings are 68.71 11), 63.92 (16) and 70.81 (15)°. In the crystal, the phenanthroline mol­ecules are linked via the solvent mol­ecule by N—H...O, O—H...N and C—H...O hydrogen bonds, leading to the formation of zigzag chains propagating along [010]. These chains are linked via C—H...N hydrogen bonds, forming undulating two-dimensional networks extending in the a- and b-axis directions.
