title: (E)-N'-(3,5-Dibromo-2-hydroxy-benzyl-idene)-4-hydroxy-benzohydrazide monohydrate.
abstract: The title compound, C(14)H(10)Br(2)N(2)O(3)·H(2)O, was synthesized by the reaction of 3,5-dibromo-2-hydroxy-benzaldehyde with an equimolar amount of 4-hydroxy-benzohydrazide in methanol. The structure comprises a Schiff base unit and a water mol-ecule of crystallization. The dihedral angle between the benzene rings in the Schiff base is 1.3 (3)°. In the crystal structure, mol-ecules are linked through inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, with the water mol-ecule serving as both donor and acceptor. As a result, layers are formed, which are approximately parallel to the bc plane.
