Ethyl 2-(3,5-dimethyl-1,1-dioxo-2H-1λ6,2,6-thiadiazin-4-yl)benzoate

Abstract

In the title compound, C14H16N2O4S, the thiadiazine ring is in a half-boat conformation. The aromatic ring deviates from the plane of this moiety at an angle of 74.6 (2)°. The structure displays intermolecular N—H...O hydrogen bonding [N...O = 2.8157 (16) Å], creating ribbons along the [010] axis. There are also weak C—H...O interactions in the crystal but no π–π stacking.
