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′-tri­cadmium

In the title linear homo-trinuclear complex, [Cd(3)(C(19)H(18)Cl(2)N(2)O(2))(2)(C(2)H(3)O(2))(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 CdN(2)C(3) 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.
