title: 1-(10H-phenothia-zin-10-yl)ethanone.
abstract: In the title compound, C14H11NOS, the phenothia-zine unit has a butterfly conformation and the central six-membered ring has a boat form. The fold angle between the benzene rings is 46.39 (7)°, which is larger than found in similar compounds, probably as a result of steric repulsion between the phenothia-zine fragment and the acetyl group.
