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-HO hydrogen bond occurs. In the crystal, molecules are linked into layers by N-HO and C-HO hydrogen bonds, generating an infinite two-dimensional network.
