چکیده
The title Schiff base compound, C(14)H(9)Br(2)ClN(2)O(2)·CH(4)O, was derived from the condensation reaction of 3,5-dibromo-salicylaldehyde with 2-chloro-benzohydrazide. The dihedral angle between the two benzene rings is 48.2 (2)°. In the crystal structure, mol-ecules are linked through O-H⋯O and N-H⋯O inter-molecular hydrogen bonds, forming layers parallel to the bc plane. There is also an O-H⋯N intramolecular hydrogen bond.
