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-HO), and some weak OCu and NCu interactions are also observed. These interactions generate a two-dimensional infinite layer.
