2-Acetyl-3-methyl-4H-1,4-benzothiazine: a redetermination at 100 K

Abstract

The structure of the title compound, C11H11NOS, has been reported previously at room temperature by Ferguson & Ruhl [Cryst. Struct. Commun. (1982), 11, 1033-1038]. We report here a redetermination, at 100 (2) K, with improved precision. The structure displays N-H center dot center dot center dot O hydrogen bonding.
