Polythia­zide

The crystal structure of the title compound, C(11)H(13)ClF(3)N(3)O(4)S(3) (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: 346–18–9), exhibits a two-dimensional network of hydrogen-bonded mol­ecules parallel to ([Image: see text]01). The NH and NH(2) groups act as donor sites and the sulfonyl O atoms as acceptor sites in N—H⋯O hydrogen bonds, and a C—H⋯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.
