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 CdII 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.
