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

In the title dinuclear Cu(II)–Lu(III) salen-type complex, [CuLu(C(22)H(24)N(2)O(4))(NO(3))(3)], with the ligand 6,6′-dimeth­oxy-2,2′-[cyclo­hexane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolate, the irregular nine-coordinate Lu(III) 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 Cu(II) 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.
