Abstract

The asymmetric unit of the title compound, C(20)H(18)ClN(5)O(3)S, contains two independent mol-ecules with significantly different conformations of the heterocyclic thia-zine rings. In both mol-ecules, the thia-zine rings adopt half-chair conformations, with the S atoms displaced by 0.382 (3) and 0.533 (3) Å and N atoms -0.351 and -0.275 Å, respectively… (More)
