چکیده
In the title compound, C(16)H(14)Br(2)N(2), the complete molecule is generated by a crystallographic twofold axis. The dihedral angle between the two benzene rings is 35.28 (8)° and that between the best planes of two ethyl-idinehydrazine N-N=C-Me units is 87.67 (11)°. Each of these N/N/C/C planes makes a dihedral angle of 63.81 (10)° with the adjacent benzene ring. In the crystal, the mol-ecules are arranged into a layer parallel to the ac plane through C-H⋯π inter-actions. C⋯Br short contacts [3.4032 (18)-3.5969 (19) Å] are also observed.

The six-membered heterocycle in the title compound, C(18)H(16)BrN(3)O(4)S, adopts a sofa conformation. Intra-molecular N-H⋯N and O-H⋯O hydrogen bonds stabilize the mol-ecular conformation by forming a five- and a six-membered ring, respectively. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds.
