pubmed-article:21589340 | pubmed:abstractText | 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. | lld:pubmed |
