2-[2-(3-Methoxyphenyl)-2-oxoethyl]-1,2-benzisothiazol-3(2H)-one 1,1-dioxide

Abstract

In the title compound, C16H13NO5S, the benzothiazole unit is essentially planar [maximum deviation = 0.0501 (10) Å for the S atom] and is oriented at a dihedral angle of 67.85 (5)° with respect to the methoxy-substituted benzene ring. The mean plane of the methoxy group is oriented at 14.3 (3)° with respect to the benzene ring to which it is attached. In the crystal structure, weak C—H...O hydrogen bonds form macrocyclic rings with R22(10) and R22(12) motifs.
