Abstract

In the title compound, C16H13BrFN3O 2S, the dihedral angle between the aromatic rings is 2.55 (19)° and the C=N - N=C torsion angle is 178.9 (3)°. The conformation of the thiazine ring is an envelope, with the S atom displaced by - 0.811 (3)Å from the mean plane of the other five atoms (r.m.s. deviation = 0.042Å). In the crystal, C - H···O interactions link the molecules and weak aromatic π-π stacking between the fluorobenzene and bromobenzene rings [centroid-centroid separation = 3.720 (2)Å and interplanar angle = 2.6 (2)°] is also observed.
