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)lutetium(III)), [CuLu(C₂₁H₂₂N₂O₄)(CH₄O)(NO₃)₃] 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 [Cu(C₂₁H₂₄N₂O₄)(CH₄O)] unit uses the two ethoxy and two hydroxy O atoms to chelate the [Lu(NO₃)₃] unit. The Cu^II atom exists in a square-pyramidal geometry and the Lu^III atom in a bicapped square-antiprismatic geometry. Molecules are linked into a chain along the b axis by O-HO hydrogen bonds. Two CH₂ groups of the C₂N₂Cu ring and the H atoms of the attached methyl group are disordered equally over two positions.
