Abstract
The title complex (systematic name: diaqua{6,6′‐dimethoxy‐2,2′‐[1,2‐ethanediylbis(nitrilomethylidyne)]diphenolato}dinitratosamarium(III)copper(II) nitrate), [CuSm(C18H18N2O4)(NO3)2(H2O)2]NO3, is composed of a discrete dinuclear cation with a salen‐type Schiff base ligand and one uncoordinated nitrate anion. The copper and samarium are doubly bridged by two phenolate O atoms provided by the Schiff base ligand. There are some classical intermolecular hydrogen bonds (O—H⋯O), and some weak O⋯Cu and N⋯Cu interactions are also observed. These interactions generate a two‐dimensional infinite layer.
