摘要：
Crystals of the title compound 2-acetyl-3-methyl-4H-1,4-benzothiazine 1-oxide (2), C11H11NO2S, crystallize in the monoclinic space group P2(1)/n. The cell parameters are almost identical to those of the unoxidized precursor 2-acetyl-3-methyl-4H-1,4-benzothiazine (1). The change in molecular geometry of the acetyl group with respect to the ring moiety in (2) from that in (1) is a consequence of hydrogen bonding involving the sulfoxide O atom.
