3-Hydroxy-4-nitro-6H-1,2,6-thiadiazine 1,1-dioxide

Abstract

The thiadiazine ring presents an envelope conformation, the S atom being at the flap. The molecules are held together by hydrogen bonds.

1,2,6-Thiadiazin-3,5(2H,6H)-dione 1,1-dioxide derivatives: crystal structure, physico-chemical and biological properties

“…Figures 1 and 2 are perspective drawings of their final X-ray models (13). A list of bond lengths and bond angles is given in Tables 3 and 4, which compare well with other thiadiazine compounds (1,(14)(15)(16)(17)(18)(19)(20), taking into account the different location of the double bonds within these molecules.…”
