3-(6-Fluoro-4-oxo-4H-chromen-3-yl)-3,4-dihydro-2H-1,2,4-benzothiadiazine-1,1-dione

Abstract

In the title compound, C16H11FN2O4S, the mean planes of the bicyclic chromone system and of the benzene ring of the benzothiadiazine derivative make a dihedral angle of 54.28 (5)°. An intramolecular N—H...O hydrogen bond occurs. In the crystal, molecules are linked into layers by N—H...O and C—H...O hydrogen bonds, generating an infinite two-dimensional network.
