4-[(E)-({4-[(4-Aminophenyl)sulfonyl]phenyl}imino)methyl]phenol ethanol monosolvate

In the title compound, C19H16N2O3S·C2H6O, the 4-hydroxybenzylidene group is oriented at dihedral angles of 73.17 (7) and 77.06 (7)° with respect to the aniline groups. The sulfonyl group make dihedral angles of 44.89 (13) and 59.16 (12)° with the adjacent aniline groups. In the crystal, a two-dimensional polymeric network parallel to (010) is formed by N—H...O, O—H...N and O—H...O hydrogen bonds. There also exist π–π interactions with a distance of 3.5976 (18) between the centroids of hydroxyphenyl rings.
