Di-μ(2)-acetato-1:2κ(2) O:O′;2:3κ(2) O:O′-bis­{μ(2)-4,4′-dichloro-2,2′-[2,2-dimethyl­propane-1,3-diylbis(nitrilo­methanylyl­idene)]diphenolato}-1:2κ(6) O,N,N′,O′:O,O′;2:3κ(6) O,O′:O,N,N′,O′-tricopper(II)

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 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 Cu⋯Cu distance is 3.0910 (5) Å. An intra­molecular 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.
