10-Methyl-10H-phenothiazine

Abstract

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.

“…In the title compound, the phenothiazine moiety has a nonplanar butterfly structure ( Fig. 1), similar to that observed for 10-methyl-10H-phenothiazine (Malikireddy et al, 2016). The central six-membered ring (N2/C18/C19/S1/C28/C23) adopts a boat conformation [puckering parameters are: Q T = 0.4567 (16) Å , = 102.8 (2) , ' = 182.8 (2) ].…”
