In the title complex, [CuSm(C₁₉H₂₀N₂O₄)(NO₃)₃]·CH₃CO-CH₃, the Cu^II atom is four-coordinated in a square-planar geometry by two O atoms and two N atoms of the deprotonated Schiff base. The Sm^III atom is ten-coordinate, chelated by three nitrate groups and linked to the four O atoms of the deprotonated Schiff base.
