{μ-6,6′-Dimethoxy-2,2′-[cyclohexane-1,2-diylbis(nitrilomethylidyne)]diphenolato}methanol-μ-nitrato-dinitratocopper(II)europium(III)

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.

“…The salen-type ligand was synthesized following the reference (Bao et al 2010). To a 1:1 MeOH/CH 2 Cl 2 solution (20 mL) of LCuH 2 O (0.0980 g, 0.2 mmol) was added SmCl 3˙6 H 2 O (0.0728 g, 0.2 mmol) at the room temperature.…”
