6-Bromo-1-methyl-4-[2-(1-phenyl-ethyl-idene)hydrazinyl-idene]-3,4-dihydro-1H-2λ(6),1-benzothia-zine-2,2-dione.

Abstract

In the title compound, C(17)H(16)BrN(3)O(2)S, the dihedral angle between the aromatic rings is 1.24 (15)° and the C=N-N=C torsion angle is 167.7 (3)°. The conformation of the thia-zine ring is an envelope, with the S atom displaced by 0.805 (3) Å from the mean plane of the other five atoms (r.m.s. deviation = 0.027 Å). In the crystal, C-H⋯O inter-actions link the mol-ecules into C(10) [010] chains. A weak C-H⋯π inter-action is also observed.
