Abstract: The title compound, [Cu₃(C₁₉H₁₈Cl₂N₂O₂)₂(CH₃CO₂)₂], is a linear homo-trinuclear Cu^II complex. The central Cu^II atom is located on a centre of inversion and has a distorted octahedral coordination environment formed by six O atoms from two tetradentate Schiff base ligands and two bridging acetate ligands. The coordination geometry of the terminal Cu^II atom is square-pyramidal with a tetradentate ligand in the basal plane. The apical site is occupied by one O atom from an acetate ligand. The acetate-bridged CuCu distance is 3.0910 (5) Å. An intramolecular C-HO hydrogen bond forms an S(6) ring motif. The crystal of the trinuclear complex is stabilized by C-HO hydrogen bonds.
