title: 1-(5,5-Dioxido-10H-phenothia-zin-10-yl)ethanone.
abstract: In the title compound, C(14)H(11)NO(3)S, the six-membered thia-zine ring fused to two benzene rings adopts a distorted boat conformation. The dihedral angle between the mean planes of the two benzene rings is 45.8 (1)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O inter-actions.
