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