%X The crystal structure of the title compound, C11H13ClF3N3O4S3 (systematic name: 6-chloro-2-methyl-3-{[(2,2,2-trifluoroethyl)sulfanyl]methyl}-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide; CRN: 346¨C18¨C9), exhibits a two-dimensional network of hydrogen-bonded molecules parallel to (overline{1}01). The NH and NH2 groups act as donor sites and the sulfonyl O atoms as acceptor sites in N¡ªH...O hydrogen bonds, and a C¡ªH...O interaction also occurs. The thiadiazine ring adopts an envelope conformation with the N atom bonded to sulfur at the tip of the flap, and the methyl substituent is in an axial position.
