Abstract: In the title complex (systematic name: (acetone-2O){6,6'-dimethoxy-2,2'-[propane-1,2-diylbis(nitrilomethylidyne)]diphenolato-1⁴O¹,O^1',O⁶,O^6':2⁴O¹,N,N',O^1'}trinitrato-1⁶O,O'-copper(II)praseodymium(III)), [CuPr(C₁₉H₂₀N₂O₄)(NO₃)₃(C₃H₆O)], the Cu^II ion is five-coordinated by two O atoms and two N atoms of the deprotonated Schiff base and by the acetone, giving rise to a square-pyramidal geometry, whereas the Pr^III ion is ten-coordinated by six nitrate O atoms and four O atoms of the deprotonated Schiff base. The C atoms, with attached H atoms, of the diaminopropane link are disordered over two positions with site occupancy factors of ca 0.7 and 0.3.
