Di-μ3-acetato-bis{μ-6,6′-diethoxy-2,2′-[propane-1,2-diylbis(nitrilomethanylylidene)]diphenolato}dicadmiumdisodium ethanol 0.67-solvate

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—H⋯O 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.
