Abstract
In the title heteronuclear ZnII–CeIII complex (systematic name: {6,6′-diethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato-1κ4O1,O1′,O6,O6′:2κ4O1,N,N′,O1′}trinitrato-1κ6O,O′-cerium(III)zinc(II)), [CeZn(C20H22N2O4)(NO3)3], with the hexadentate Schiff base compartmental ligand N,N′-bis(3-ethoxysalicylidene)ethylenediamine, the Zn and Ce atoms are doubly bridged by two phenolate O atoms provided by the Schiff base ligand. The coordination of the Zn atom is square planar with the donor centers of two imine N atoms and two phenolate O atoms. The cerium(III) center has a decacoordination environment of O atoms, involving the phenolate O atoms, two ethoxy O atoms and two O atoms each from the three nitrate ligands. Some weak C—H⋯O and O⋯Zn [O⋯Zn = 3.156 (4) Å] interactions generate a two-dimensional zigzag sheet.
