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, [ZnBr 2 (C 22 H 19 ClN 4 O)], 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 R 2 2 (22) and R 2 2 (14) rings. These ribbons are linked through an inter­molecular C—H⋯Br hydrogen bond, forming a two-dimensional network sheet.
