6-Bromo-4-hydrazinyl-idene-1-methyl-3H-2 6,1-benzothiazine-2,2- dione

Abstract

In the title molecule, C 9H 10BrN 3O 2S, the thia-zine ring has an envelope conformation with the S atom at the flap. The geometry around the S atom is distorted tetra-hedral. In the crystal, inversion dimers linked by pairs of N - H⋯N hydrogen bonds occur, generating R 22(6) ring motifs. N - H⋯O hydrogen bonds and C - H⋯O interactions connect the dimers, forming a three-dimentional network structure.
