Abstract: In the crystal of the title compound, [Cd₂Na₂(C₂H₃O₂)₂(C₂₁H₂₄N₂O₄)₂]·0.67C₂H₆O, the doubly deprotonated Schiff base ligand N,N',O,O'-chelates to the Cd^II cation, which is also O,O'-chelated by the acetate ion. Two Cd-Schiff base units are connected to two Na⁺ atoms to form the tetranuclear complex, in which the Cd²⁺ and Na⁺ cations show distorted octahedral coordinations. The asymmetric unit consists of half a tetranuclear molecule (lying on an inversion center) and a full tetranuclear molecule (lying on a general position) along with a lattice ethanol molecule, which links to the coordinating acetate ion via an O-HO hydrogen bond. In the crystal, the propyl and ethyl groups of the complex molecule are disordered over two positions in a 1:1 ratio; the ethyl group of the lattice ethanol molecule is also equally disordered over two positions.
