Abstract
In the title dinuclear salen-type complex, [CuEu(C22H24N2O4)(NO3)3(CH3OH)], the CuII ion is five-coordinated to two imine N atoms and two phenolate O atoms and one O from the bridging nitrate group. The EuIII ion is ligated to three nitrate groups, four O atoms from the salen-type ligand and one methanol molecule, leading to a distorted tenfold coordination for the rare earth cation. One of the three nitrate anions is disordered over two positions in a 0.66 (5):0.34 (5) ratio.
