In the title heteronuclear Zn-II-Sm-III complex, [SmZn(C18H18-N2O4)(NO3)(3)(CH3CH2OH)], with the hexadentate Schiff base compartmental ligand N,N'-bis(3-methoxysalicylidene)ethylenediamine (H2L), 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 center dot center dot center dot O and C-H center dot center dot center dot O interactions generate a layer structure extending parallel to (101).
