Abstract:
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'-dimeth-oxy-2,2'-[cyclo-hexane-1,2-diylbis(nitrilo-methyl-idyne)]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 mol-ecule [Cu-O = 1.897 (3) and 1.906 (3) Å]. All atoms of the cyclo-hexane ring of the ligand mol-ecule are disordered over two sets of sites with equal occupancy.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
