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, C(15)H(18)BrN(3)O(2)S, contains two independent mol-ecules in both of which the (thia-zine)C=N-N double bond exhibits an E conformation. The cyclo-hexyl rings adopt chair conformations while the thia-zine 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 mo...
