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

ABSTRACT: In the title compound, C(16)H(11)FN(2)O(4)S, the mean planes of the bicyclic chromone system and of the benzene ring of the benzothia-diazine derivative make a dihedral angle of 54.28?(5)°. An intra-molecular N-H?O hydrogen bond occurs. In the crystal, mol-ecules are linked into layers by N-H?O and C-H?O hydrogen bonds, generating an infinite two-dimensional network.
