(2Z)-2-(4-Chlorobenzylidene)-4-[2-(2-oxooxazoliden-3-yl)ethyl]-3,4-dihydro-2H-1,4-benzothiazin-3-one

Abstract

In the title molecule, C20H17ClN2O3S, the oxazolidine ring is oriented towards the benzothiazine moiety so that the centroid of the former is ca 5.05 Å from the sulfur atom of the latter. In the crystal, the molecules are arranged in layers parallel to (101) and held together by the aid of C—H...O interactions, resulting in a three-dimensional network structure.
