In the title compound, a pheno­thia­zine moiety is linked to a planar carbazole unit (r.m.s. deviation = 0.029 Å) by a C—C single bond. Their mean planes are inclined to one another by 27.28 (5)°, and the pheno­thia­zine moiety possesses a typical butterfly structure with a fold angle of 27.36 (9)° between the two benzene rings.

In the title compound C13H11NS, the phenothiazine unit has a non-planar butterfly structure, and the central six-membered ring adopts a boat conformation. The dihedral angle between the two outer aromatic rings of the phenothiazine unit is 39.53 (10)°. In the crystal, a π–π interaction with a centroid–centroid distance of 3.6871 (12) Å is observed between the aromatic rings of neighbouring molecules.
