Abstract: The Cu atom in the title compound (systematic name: {6,6'-diethoxy-2,2'-[propane-1,2-diylbis(nitrilomethylidyne)]diphenolato-1⁴O¹,O^1',O⁶,O^6':2⁴O¹,N,N',O^1'}(methanol-2O)trinitrato-1⁶O,O'-copper(II)neodymium(III)), [CuNd(C₂₁H₂₂N₂O₄)(NO₃)₃(CH₄O)], is N,N',O,O'-chelated by the deprotonated Schiff base, the four chelating atoms forming a square plane above which lies the methanol molecule. The (C₂₁H₂₄N₂O₄)(CH₄O)Cu unit uses the two ethoxy and two hydroxy O atoms to chelate the (NO₃)₃Nd unit. The Cu^II atom exists in a square-pyramidal geometry and the Nd^III atom in a bicapped square-antiprismatic geometry. Molecules are linked by O-HO hydrogen bonds into a linear chain along the b axis. Some C and H atoms of the Schiff base are disordered equally over two positions.
