Study on the interactions of nitrophenols with bis-8-hydroxyquinolinium zinc-2,6-pyridinedicarboxylate

Crystal structure of (7-{[bis(pyridin-2-ylmethyl)amino-κ3 N,N′,N′′]methyl}-5-chloroquinolin-8-ol)dibromidozinc(II)

In the title compound, the Zn^II atom has a distorted square-pyramidal coordination environment. The mol­ecular structure exhibits an intra­molecular O—H⋯N hydrogen bond. In the crystal, the mol­ecules are linked by inter­molecular C—H⋯Br hydrogen bonds, generating ribbon structures. These ribbons are linked though inter­molecular C—H⋯Br hydrogen bonds, forming a two-dimensional network sheet.

In the title compound, [ZnBr₂(C₂₂H₁₉ClN₄O)], the Zn^II atom adopts a distorted square-pyramidal coordination geometry, formed by two bromido ligands and three N atoms of the bis­(pyridin-2-ylmeth­yl)amine moiety in the penta­dentate ligand containing quinolinol. The Zn^II atom is located well above the mean basal plane of the square-based pyramid. The apical position is occupied by a Br atom. The O and N atoms of the quinolinol moiety in the ligand are not coordinated to the Zn^II atom. An intra­molecular O—H⋯N hydrogen bond, generating an S(5) ring motif, stabilizes the mol­ecular structure. In the crystal, the mol­ecules are linked by inter­molecular C—H⋯Br hydrogen bonds, generating ribbon structures containing alternating R₂²(22) and R₂²(14) rings. These ribbons are linked through an inter­molecular C—H⋯Br hydrogen bond, forming a two-dimensional network sheet.
