S. Umezono and T. Okuno

Abstract: In the title compound, C₁₅H₁₁NS, the asymmetric unit comprises one half-molecule; a mirror plane passes through the S atom, the ynamine fragment, the methyl C atom and one methyl H atom. The phenothiazine moiety has a butterfly conformation and the central six-membered ring has a boat conformation. The dihedral angle between the benzene rings is 149.40 (4)°. The crystal structure is stabilized by van der Waals interactions.
