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

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

{μ-6,6′-Dimeth­oxy-2,2′-[cyclo­hexane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolato}trinitratocopper(II)lutetium(III)

In the title dinuclear CuII–LuIII salen-type complex, [CuLu(C22H24N2O4)(NO3)3], with the ligand 6,6′-dimeth­oxy-2,2′-[cyclo­hexane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolate, the irregular nine-coordinate LuIII coordination sphere comprises four O atoms from the ligand and five O atoms from three nitrate groups, two bidentate and one monodentate [Lu—O = 2.230 (3)–2.621 (4) Å]. The slightly distorted square-planar four-coordinate CuII atom comprises two imine N atoms [Cu—N = 1.903 (4) and 1.912 (4) Å] and two phenolate O atoms from the ligand mol­ecule [Cu—O = 1.897 (3) and 1.906 (3) Å]. All atoms of the cyclo­hexane ring of the ligand mol­ecule are disordered over two sets of sites with equal occupancy
