2-(2-Oxo-2-phenylethyl)-1,2-benzisothiazol-3(2H)-one 1,1-dioxide

Abstract

In the title compound, C15H11NO4S, the benzothiazole unit is essentially planar [maximum deviation = 0.0644 (14) Å for the N atom] and forms a dihedral angle 54.43 (6)° with the phenyl ring. In the crystal structure, weak bifurcated C—H...O hydrogen bonds involving the carbonyl O atoms as acceptors result in R22(7) ring motifs.
