Abstract: The title heteronuclear Ni^II-Y^III complex (systematic name: {6,6'-diethoxy-2,2'-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato-1⁴O¹,O^1',O⁶,O^6':2⁴O¹,N,N',O^1'}trinitrato-1⁶O,O'-yttrium(III)nickel(II)), [NiY(C₂₀H₂₂N₂O₄)(NO₃)₃], with the hexadentate Schiff base compartmental ligand N,N'-bis(3-ethoxysalicylidene)ethylenediamine (H₂L), has been synthesized and structurally characterized. The Ni and Y atoms are doubly bridged by two phenolate O atoms provided by the Schiff base ligand. The coordination of the Ni atom is square planar, formed by two imine N atoms and two phenolate O atoms. The Y^III atom has a decacoordination environment of O atoms, formed by the phenolate O atoms, two ethoxy O atoms and two O atoms each from three nitrate ligands. No classical intermolecular hydrogen bonds are found. Some weak C-HO and ONi interactions generate a two-dimensional zigzag sheet.
