4-[(E)-({4-[(4-Amino-phen-yl)sulfon-yl]phen-yl}imino)-meth-yl]phenol ethanol monosolvate
Abstract:
In the title compound, C(19)H(16)N(2)O(3)S·C(2)H(6)O, the 4-hy-droxy-benzyl-idene 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 inter-actions with a distance of 3.5976 (18) Å between the centroids of hy-droxy-phenyl rings.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
