Abstract
In the title compound, C17H17N3O2S, the dihedral angle between the aromatic rings is 6.3 (5)° and the C=N—N=C group is statistically planar [torsion angle = 179.8 (8)°]. The conformation of the thiazine ring is an envelope, with the S atom displaced by 0.823 (9) Å from the mean plane of the other five atoms (r.m.s. deviation = 0.012 Å). In the crystal, C—H⋯O interactions link the molecules into C(5) chains propagating along [101]. The chains are consolidated by weak aromatic π–π stacking between the benzene and toluene rings [centroid-to-centroid separation = 3.826 (5) Å and interplanar angle = 6.3 (4)°].
