Abstract

Crystallography Physical Sciences Science & Technology
In the title molecule, C9H10BrN3O2S, the thiazine ring has an envelope conformation with the S atom at the flap. The geometry around the S atom is distorted tetrahedral. In the crystal, inversion dimers linked by pairs of N-H center dot center dot center dot N hydrogen bonds occur, generating R-2(2)(6) ring motifs. N-H center dot center dot center dot O hydrogen bonds and C-H center dot center dot center dot O interactions connect the dimers, forming a three-dimentional network structure.
