N′-(3-Bromo-5-chloro-2-hydroxybenzylidene)-4-hydroxybenzohydrazide
The mol-ecule of the title compound, C(14)H(10)BrClN(2)O(3), is planar [dihedral angle between the aromatic rings = 3.0 (2)°] and shows a trans configuration with respect to the C=N double bond. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds and an intramolecular O-H⋯N interaction also occurs.

In the approximately planar title mol-ecule, C(14)H(10)BrClN(3)O(2), the dihedral angle between the aromatic ring planes is 5.79 (12)°. The conformation is stabilized by intra-molecular O-H⋯N and N-H⋯O hydrogen bonds and an inter-molecular O-H⋯O link leads to chains in the crystal propagating in [001].

The title compound, C(15)H(12)BrClN(2)O(3), was obtained by the condensation reaction between 3-bromo-5-chloro-2-hydroxy-benzaldehyde and 2-methoxy-benzohydrazide. The mol-ecule is essentially planar, with a dihedral angle between the two benzene rings of 4.7 (2)°, and displays an E configuration about the C=N double bond. The mol-ecular conformation is stabilized by intramolecular O-H⋯N and N-...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(9)BrClN(3)O(2), in which the dihedral angles between the benzene and pyridine rings are 8.23 (9)° and 52.84 (12)°. Both the mol-ecules exist in an E configuration with respect to the C=N double bond. The two mol-ecules in the asymmetric unit are linked via weak C-H⋯O hydrogen bonds. In both the mol-ecules,...

In the title compound, C(18)H(18)BrClN(2)O(2)·C(2)H(6)O, the hy-droxy group forms an intra-molecular O-H⋯N hydrogen bond, which influences the conformation of the Shiff base mol-ecule, where the two aromatic rings form a dihedral angle of 21.67 (8)°. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link two Shiff base mol-ecules and two solvent mol-ecules into a centrosymmetric heterotetra-mer. W...
