title: (4Z)-1-Methyl-4-[(2E)-2-(4-methyl-benzyl-idene)hydrazin-1-yl-idene]-3,4-dihydro-1H-2λ(6),1-benzothia-zine-2,2-dione.
abstract: In the title compound, C(17)H(17)N(3)O(2)S, 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 thia-zine 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 inter-actions link the mol-ecules 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 inter-planar angle = 6.3 (4)°].
