{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(C22H24N2O4)(NO3)(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) angstrom]. The slightly distorted square-planar four-coordinate Cu-II atom comprises two imine N atoms [Cu-N = 1.903 (4) and 1.912 (4) angstrom] and two phenolate O atoms from the ligand molecule [Cu-O = 1.897 (3) and 1.906 (3) angstrom]. All atoms of the cyclohexane ring of the ligand molecule are disordered over two sets of sites with equal occupancy.
