摘要
In the title compound, C17H16BrN3O2S, the dihedral angle between the aromatic rings is 1.24 (15)~ and the C=N〞N=C torsion angle is 167.7 (3)~. The conformation of the thiazine ring is an envelope, with the S atom displaced by 0.805 (3) from the mean plane of the other five atoms (r.m.s. deviation = 0.027 ). In the crystal, C〞H...O interactions link the molecules into C(10) [010] chains. A weak C〞H...羽 interaction is also observed.
