Abstract
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)degrees in the two independent molecules while the aromatic and thiazine rings are twisted by dihedral angles of 8.73 (8) and 13.07 (2)degrees respectively. In the crystal, C - H...O and C-H...Br interactions connect molecules into chains propagating along the a axis.
