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—HO, O—HN and C—HO hydrogen bonds, leading to the formation of zigzag chains propagating along [010]. These chains are linked via C—HN hydrogen bonds, forming undulating two-dimensional networks extending in the a- and b-axis directions.

There are two independent molecules in the asymmetric unit of the title molecule, C8H9N3S2, both of which exhibit an E conformation with the pyridine ring and dithiocarbazate fragment located on opposite sides of the C=N bond. The pyridine ring and dithiocarbazate group are approximately coplanar, with dihedral angles of 4.74 (1) and 8.77 (1)° between their planes in the two molecules. In the crystal, molecules are linked to each other via N—HN hydrogen bonds, forming zigzag chains parallel to [10-1].
