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) Å between the centroids of hy­droxy­phenyl rings.

N,N-Bis(2-hy­droxy­eth­yl)-4-methyl­benzene­sulfonamide

In the title compound C₁₁H₁₇NO₄S, an intra­molecular O—H...O hydrogen bond forms an S(8) ring and determines the conformation of the bis­(2-hy­droxy­eth­yl) segment of the mol­ecule, holding the two CH₂CH₂OH groups close to coplanar (r.m.s. deviation = 0.185 Å). In the crystal, O—H...O hydrogen bonds link the mol­ecules into zigzag chains along the b axis. Weaker additional C—H...O and C—H...π contacts generate a three dimensional network, with mol­ecules stacked along the b-axis direction.
