Di-μ₂-acetato-1:2κ² O:O′;2: 3κ² O:O′-bis{μ₂-4,4′-dichloro-2, 2′-[2,2-dimethylpropane-1,3-diylbis(nitrilomethanylylidene)]diphenolato} -1:2κ⁶ O,N,N′,O′:O,O′;2:3κ⁶ O,O′:O,N,N′,O′-tricadmium

In the title linear homo-trinuclear complex, [Cd₃(C ₁₉H₁₈Cl₂N₂O₂)2(C ₂H₃O₂)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 CdN₂C 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.
