N′-(5-Bromo-2-hydroxybenzylidene)-3-hydroxybenzohydrazide

Abstract

The asymmetric unit of the title compound, C14H11BrN2O3, contains two crystallographically independent mol­ecules with slightly different conformations with respect to the aromatic rings; the dihedral angles between the two benzene rings in the two mol­ecules are 55.0 (7) and 16.3 (7)°. In the crystal structure, mol­ecules are linked through inter­molecular N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds, forming chains running along the a axis.
