2-Amino-4-(4-chloro-1-ethyl-2,2-dioxo-1-benzo[][1,2]thia-zin-3-yl)-7,7-dimethyl-5-oxo-5,6,7,8-tetra-hydro-4-chromene-3-carbo-nitrile: single-crystal X-ray diffraction study and Hirshfeld surface analysis.

In the title compound, CHClNOS, which has potential non-steroidal anti-inflammatory activity, the benzo-thia-zine and cyclo-hexenone rings both adopt a distorted sofa conformation while the 4-pyrane ring adopts a very flattened sofa conformation. The two bicyclic fragments are skewed to each other, with the dihedral angle between their least-squares planes being 72.8 (1)°.
