4-Benzoyloxy-2-methyl-N-(2-pyridyl)-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide

Abstract

The crystal structure of the title compound, C(22)H(17)N(3)O(5)S, contains dimers linked by N-H...O hydrogen bonds about inversion centers. The dimers are packed in a herring-bone framework without classical hydrogen bonds between the structure-forming units.

N-Butyl-4-hydroxy-2-methyl-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide

“…The 14-membered rings thus formed represent R 2 2 (14) motif in the graph set notation (Bernstein et al, 1994). Similar hydrogen-bonded dimers have been reported in structures related to the title compound Drebushchak et al, 2006;Kojić-Prodić & Rużić-Toroš, 1982). The structure is stabilized by extensive intramolecular interactions ( Fig.…”
