Abstract:
There are two mol-ecules, A and B, in the asymmetric unit of the title compound, C14H16N2O4S, which is the first example reported in this family of compounds in which the Nsp(3) atom of the thia-diazine ring is methyl-ated. The thia-diazine rings adopt shallow envelope conformations, with the S atoms displaced by 0.319 (12) and 0.182 (12) Å from the mean planes of the other ring atoms in mol-ecules A and B, respectively. The dihedral angles between the thia-diazine mean planes (excluding S) and the attached benzene rings are 86.8 (3) and 86.7 (3)° for mol-ecules A and B, respectively.
