R factor = 0.065; wR factor = 0.210; data-to-parameter ratio = 15.3. The title compound, C32H21N4C2H5OH, 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.
