Abstract: There are two unique molecules of the title mononuclear zinc(II) complex, [Zn(C₂₀H₁₂Cl₂N₂O₂)(C₅H₅N)], in the asymmetric unit. The Zn^II ion is five-coordinate in a distorted square-pyramidal geometry, with the basal plane defined by the two N and two O atoms of the Schiff base ligand and the apical position occupied by the N atom of the pyridine. The N and O atoms of the Schiff base ligand are mutually cis. The molecules are linked by weak C-HCl interactions into chains along the b axis. Other molecules are arranged diagonally between adjacent chains and bridge the chains through weak C-HO interactions. The crystal structure is further stabilized by weak intra- and intermolecular C-HO hydrogen bonds and C-H interactions.
