Abstract: The title complex (systematic name: {2,2'-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato-1⁴O¹,O^1',O⁶,O^6':2⁴O¹,N,N',O^1'}(methanol-1O)trinitrato-1⁶O,O'-copper(II)europium(III)), [CuEu(C₁₆H₁₄N₂O₂)(NO₃)₃(CH₃OH)], is a heterodinuclear 3d-4f metal Schiff base dimer. The Cu^II ion is five-coordinated by two O atoms, two N atoms of the deprotonated Schiff base and one nitrate O atom from a neighboring dinuclear unit, giving rise to a square-pyramidal geometry, whereas the Eu^III ion is nine-coordinated by six O atoms from nitrate groups, two O atoms from the deprotonated Schiff base and one O atom from methanol. The ethylene link is disordered over two positions with a site occupancy ratio of ca 3:1. The crystal structure involves O-HO hydrogen bonds.
