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 octa-hedral coordination geometry formed by four O atoms from two bidentate/tetra-dentate 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 tetra-dentate 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 supra-molecular network structure lying parallel to the ab plane.
