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

In the title compound, C(19)H(16)N(2)O(3)S·C(2)H(6)O, 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) Å between the centroids of hy­droxy­phenyl rings.
