The structure of the title compound, [Cu{Cu(CH3CO2)(C17H16N2O2)}(2)]. C4H8O2, contains a linear homotrinuclear complex with a central Cu-II ion which lies on an inversion centre. It has an irregular octahedral coordination involving four O atoms from two N,N'-bis(salicylidene)-1,3-propanediaminato (SALPD(2-)) ligands and two acetate groups. The coordination about each of the two terminal Cu-II ions related by the inversion centre comprises two O atoms and two N atoms from an SALPD(2-) ligand, as well as one acetate O atom. Each acetate anion bridges between a terminal and the central Cu-II ion, and these are mutually trans. The Cu Cu bridging distance is 3.1242(7)Angstrom. Taking into account that the dioxane molecules bridge trinuclear complexes in neighbouring unit cells through Cu2 ... O5 contacts of 2.649(3) Angstrom, each terminal Cu-II ion possesses irregular octahedral coordination.
