Abstract
In the title compound, C16H13Cl2N3O2S, the dihedral angle between the aromatic rings is 6.62 (2)° and the C=N - N=C torsion angle is 176.2 (4)°. The thiazine ring shows an envelope conformation, with the S atom displaced by 0.633 (6) Å from the mean plane of the other five atoms (r.m.s. deviation = 0.037 Å). The Cl atom is an an axial conformation and is displaced by 2.015 (6) Å from the thiazine ring plane. In the crystal, molecules are linked by C - H⋯O interactions, generating a three-dimensional network. Very weak aromatic π-π stacking interactions [centroid-centroid separations = 3.928 (2) Å] are also observed.
