摘要：

The molecular structure of the title compound, C16H11BrN2O4S, is very similar to that of the previously reported fluoro analogue [al-Rashida et al. (2010). Acta Cryst. E66, o2707]. The mean planes of the bicyclic chromone system and the benzene ring of the benzothiadiazine derivative make a dihedral angle of 58.23 (8)degrees. An intramolecular N-H center dot center dot center dot O hydrogen bond occurs. In the crystal, molecules are linked into layers by N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds, generating an infinite two-dimensional network.
