Descripción
Sumario:The mol­ecular structure of the title compound, C(16)H(11)BrN(2)O(4)S, 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)°. 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.
