Di-μ₂-acetato-1:2κ²O:O′;2:3κ²O:O′-bis­{μ₂-4,4′-di­chloro-2,2′-[2,2-di­methyl­propane-1,3-diylbis(nitrilo­methanylyl­idene)]diphenolato}-1:2κ⁶O,N,N′,O′:O,O′;2:3κ⁶O,O′:O,N,N′,O′-tri­cadmium

In the title linear homo-trinuclear complex, [Cd₃(C₁₉H₁₈Cl₂N₂O₂)₂(C₂H₃O₂)₂], the central Cd^II atom is located on a centre of inversion and has a distorted octa­hedral coordination geometry formed by four O atoms from two bidentate/tetra­dentate Schiff base ligands and two O atoms from two bridging acetate ligands. The coordination geometry of the terminal Cd^II atom is square-pyramidal with the tetra­dentate part of the ligand in the basal plane and one O atom from an acetate ligand occupying the apical site. The six-membered CdN₂C₃ ring adopts a chair conformation. The acetate-bridged Cd...Cd distance is 3.3071 (2) Å. The crystal structure is stabilized by C—H...O hydrogen bonds, which form C(7) chain motifs and give rise to a two-dimensional supra­molecular network structure lying parallel to the ab plane.
