{6,6′-Dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato}methanol-μ-nitrato-dinitratolutetium(III)zinc(II)

Abstract

In the title heteronuclear ZnII–LuIII complex (systematic name: {6,6′-dimeth­oxy-2,2′-[ethane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolato-1κ4O1,O1′,O6,O6′:2κ4O1,N,N′,O1′}(methanol-1κO)-μ-nitrato-1:2κ2O:O′-dinitrato-1κ4O,O′-lutetium(III)­zinc(II)), [LuZn(C18H18N2O4)(NO3)3(CH4O)], with the hexa­dentate Schiff base compartmental ligand N,N′-bis­(3-methoxy­salicyl­idene)ethyl­enediamine, the Lu and Zn atoms are triply bridged by two phenolate O atoms provided by the Schiff base ligand and one nitrate ion. The five-coordinated Zn is in a square-pyramidal geometry with the donor centers of two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms. The LuIII center has a tenfold coordination environment of O atoms, involving the phenolate O atoms, two meth­oxy O atoms, one methanol O atom, and two O atoms from two nitrate ions and one from the bridging nitrate ion. Weak inter­molecular C—H⋯O inter­actions generate a two-dimensional layer structure.
