The title compound, [Cu(3)(C(19)H(18)Cl(2)N(2)O(2))(2)(CH(3)CO(2))(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 octa-hedral coordination environment formed by six O atoms from two tetra-dentate Schiff base ligands and two bridging acetate ligands. The coordination geometry of the terminal Cu(II) atom is square-pyramidal with a tetra-dentate ligand in the basal plane. The apical site is occupied by one O atom from an acetate ligand. The acetate-bridged Cu⋯Cu distance is 3.0910 (5) Å. An intra-molecular C-H⋯O hydrogen bond forms an S(6) ring motif. The crystal of the trinuclear complex is stabilized by C-H⋯O hydrogen bonds.
