{6,6′-Dimeth­oxy-2,2′-[ethane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolato-1κ(4) O (1),O (1′),O (6),O (6′):2κ(4) O (1),N,N′,O (1′)}(ethanol-1κO)-μ-nitrato-1:2κ(2) O:O′-dinitrato-1κ(4) O,O′-samarium(III)zinc(II)

In the title heteronuclear Zn(II)–Sm(III) complex, [SmZn(C(18)H(18)N(2)O(4))(NO(3))(3)(CH(3)CH(2)OH)], with the hexa­dentate Schiff base compartmental ligand N,N′-bis­(3-methoxy­salicyl­idene)ethyl­enediamine (H(2) L), the Sm(III) and Zn(II) ions are triply bridged by two phenolate O atoms from the Schiff base ligand and one nitrate anion. The five-coordinate Zn(II) ion is in a square-pyramidal geometry formed by the donor centers of two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms. The Sm(III) center is in a ten-fold coordination of O atoms, involving the phenolate O atoms, two meth­oxy O atoms, one ethanol O atom, and two O atoms from two nitrate anions and one from the bridging nitrate anion. In the crystal, inter­molecular O—H⋯O and C—H⋯O inter­actions generate a layer structure extending parallel to (101).
