1-(10H-phenothiazin-10-yl)ethanone

E. Tokunaga and T. Okuno

Abstract: In the title compound, C₁₄H₁₁NOS, the phenothiazine 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 phenothiazine fragment and the acetyl group.
