6-Bromo-1-methyl-4-[2-(4-nitro­benzyl­idene)hydrazin-1-yl­idene]-2,2-dioxo-3,4-dihydro-1H-2λ(6),1-benzothia­zine

In the title compound, C(16)H(13)BrN(4)O(4)S, the dihedral angle between the aromatic rings is 4.1 (2)° and the C=N—N=C torsion angle is 175.5 (3)°. The nitro group is almost coplanar with the benzene ring to which it is attached [dihedral angle = 2.9 (7)°]. The thia­zine ring has an S-envelope conf...

description In the title compound, C(16)H(13)BrN(4)O(4)S, the dihedral angle between the aromatic rings is 4.1 (2)° and the C=N—N=C torsion angle is 175.5 (3)°. The nitro group is almost coplanar with the benzene ring to which it is attached [dihedral angle = 2.9 (7)°]. The thia­zine ring has an S-envelope conformation with the S atom displaced by 0.819 (3) Å from the mean plane of the other five atoms (r.m.s. deviation = 0.017 Å). In the crystal, C—H⋯O inter­actions link the mol­ecules and weak aromatic π–π stacking [centroid–centroid separation = 3.874 (2) Å] is also observed.
