Abstract
Crystals of the title compound, C(14)H(9)BrI(2)N(2)O(2)·H(2)O, were obtained from a condensation reaction of 3-bromo-benzohydrazide with 3,5-diiodo-salicylaldehyde. The Schiff base mol-ecule assumes an E configuration with respect to the C=N bond, and the dihedral angle between the two benzene rings is 6.9 (2)°. An intra-molecular O-H⋯N hydrogen bond is observed in the Schiff base mol-ecule and may contribute to its overall near planarity. In the crystal structure, mol-ecules are linked through inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, forming layers parallel to the bc plane. Short inter-molecular I⋯O contacts [2.930 (5) Å] are also found, linking the mol-ecules into zigzag chains along b.
