3-Bromo-N'-(2-hydroxy-benzyl-idene)benzohydrazide.

ABSTRACT: The title mol-ecule, C(14)H(11)BrN(2)O(2), displays a trans configuration about the C=N and C-N bonds. The dihedral angle between the two benzene rings is 18.5?(3)°. An intra-molecular O-H?N hydrogen bond is observed. In the crystal structure, the mol-ecules are linked into a chain along the c axis by N-H?O and C-H?O hydrogen bonds.
