4,6-Dichloro-2-((E)-{4-[(E)-3,5-dichloro-2-hydroxybenzylideneamino]butylimino}methyl)phenol
The asymmetric unit of the title compound, C(18)H(16)Cl(4)N(2)O(2), comprises half of a potentially tetra-dentate Schiff base ligand. It is located about a twofold rotation axis that bis-ects the central C-C bond of the butane-1,4-diamine group. There are two intra-molecular O-H⋯N hydrogen bonds making S(6) ring motifs. In the crystal, mol-ecules are linked by pairs of weak C-H⋯Cl inter-actions...

The asymmetric unit of the title compound, C(16)H(12)Cl(4)N(2)O(2), comprises half of a potentially tetra-dentate Schiff base ligand, located about a twofold rotation axis which bis-ects the central C-C bond of the ethane-1,2-diamine group. In the solid state, the compound exists in the zwitterionic form. There are two intra-molecular N-H⋯O hydrogen bonds making S(6) ring motifs. In the crystal...

In the title compound, C(19)H(18)Cl(4)N(2)O(2), a potential tetra-dentate Schiff base ligand, the dihedral angle between the two benzene rings is 48.01 (10)°. The configuration about the two C=N bonds is E and two intra-molecular O-H⋯N hydrogen bonds make S(6) ring motifs. In the crystal, mol-ecules are linked along the b axis via inter-molecular C-H⋯Cl inter-actions. The crystal structure is f...

In the title compound, C(15)H(12)Cl(2)N(2)O(3), the dihedral angle between the two substituted aromatic rings is 5.4 (4)°. Intra-molecular O-H⋯N and N-H⋯O hydrogen bonds affect the planarity of the molcular conformation, with a mean deviation from the plane defined by the non-H atoms of 0.062 (2) Å. The mol-ecule exists in a trans configuration with respect to the methyl-idene unit. In the crys...

The two symmetry independent mol-ecules of the title compound, C(19)H(13)Cl(2)NO(4), show similar conformations with the acetyl group twisted strongly relative to the remaining, virtually flat (r.m.s. deviations = 0.0173 and 0.0065 Å), part of the mol-ecule. The hydroxyl groups of the 8-hydroxy-quinoline residues are involved in intra-molecular O-H⋯N hydrogen bonds, which, in one case, forms a ...
