A heteronuclear Zn(II)-Eu(III) complex (systematic name: {6,6'-diethoxy-2,2'-[ethane-1,2-diylbis(nitrilomethylidyne)] diphenolato-1K(4)O(1),O(1'),O(6),O(6'):2K(4)O(1),N,N',O(1')}trinitrato-1K(6)O,O'- europium(III)zinc(II)), [EuZn(C(20)H(22)N(2)O(4))(NO(3))(3)], with the hexadentate Schiff base compartmental ligand N,N'-bis(3-ethoxysalicylidene)ethylenediamine, has been synthesized and structurally characterized. The Zn and Eu atoms are doubly bridged by two phenolate O atoms provided by the Schiff base ligand. The coordination of Zn is square planar with the donor centers of two imine N atoms and two phenolate O atoms. The Eu center has a decacoordination environment formed by the phenolate O atoms, two ethoxy O atoms and two O atoms from each of the three nitrates. No classical intermolecular hydrogen bonds are found. Some weak C-H center dot center dot center dot O and O center dot center dot center dot Zn interactions [O center dot center dot center dot Zn = 3.193 (4) angstrom] generate a two-dimensional zigzag sheet.
