6-Bromo-4-(2-cyclo­hexyl­idenehydrazin-1-yl­idene)-1-methyl-2,2-dioxo-3,4-dihydro-1H-2λ⁶,1-benzothia­zine

The asymmetric unit of the title compound, C₁₅H₁₈BrN₃O₂S, contains two independent mol­ecules in both of which the (thia­zine)C=N—N double bond exhibits an E conformation. The cyclo­hexyl rings adopt chair conformations while the thia­zine rings are in sofa conformations. The mean planes of these rings are oriented at dihedral angles of 64.43 (13) and 28.6 (2)° in the two independent mol­ecules while the aromatic and thia­zine rings are twisted by dihedral angles of 8.73 (8) and 13.07 (2)°, respectively. In the crystal, C—H...O and C—H...Br inter­actions connect mol­ecules into chains propagating along the a axis.
