N-(4-Hydroxy­phen­yl)-2-(113-trioxo-23-di­hydro-12-benzothia­zol-2-yl)­acet­amide

摘要

In the title compound, C15H12N2O5S, the benzisothia­zole group is approximately planar (r.m.s. deviation excluding H atoms and the two O atoms bonded to S = 0.023 Å). The dihedral angle between the benzisothia­zole ring and the terminal phenol ring is 84.9 (1)°. In the crystal, mol­ecules are joined by N—H⋯O and O—H⋯O hydrogen bonds, and π-stacking inter­actions are observed between alternating phenol and benzisothia­zole rings [centroid–centroid distances = 3.929 (3) and 3.943 (3) Å].
