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) 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.

Comment top

In a continuation of the studies of salen-type lanthanide complexes (Mohamed et al. 2003, Aslantaş et al. 2007, Sun et al. 2009), we present here the crystal structure of the Cu^II–Lu^III mixed-metal complex prepared using the ligand N,N'-bis(2-oxo-3-methoxybenzylidene)-1,2-diaminocyclohexane (H₂L), [CuLu(C₂₂H₂₄N₂O₄)(NO₃)₃], the title compound (I) (Fig. 1). The irregular LuO₉ coordination sphere of (I) comprises two phenolate and two methoxy O donors from the imine-phenolate ligand molecule and five O-donors from the three nitrate anions, two bidentate and one monodentate. The Lu—Cu distance is 3.2336 (10) Å, but is not nitrate-bridged as found in analogous lanthanide complexes (Koner et al., 2005; Sui et al., 2006; Costes et al. 2008; Bao et al. 2010). Notably, the coordinated methanol molecule found in the Cu^II–Eu^III complex (Bao et al., 2010) is absent in the structure of (I), which is consistent with the familiar lanthanide contraction concept. The Lu—O bond distance range in (I) is 2.230 (3)–2.621 (4) Å. The Cu^II ion is tetra-coordinated by two imine N atoms and two bridging phenolate O atoms from the ligand molecule and is slightly distorted square-planar[Cu—N, 1.903 (4), 1.912 (4) Å; Cu—O, 1.897 (3), 1.906 (3) Å]. All atoms of the cyclohexane ring of the ligand molecule are 50% disordered.

Experimental top

To a 2:3 MeOH/MeCN solution (35 ml) of [(H₂L)Lu(NO₃)₃] (0.2415 g, 0.3 mmol) was added an aqueous solution (10 ml) of Cu(OAc)₂ . H₂O (0.0597 g, 0.3 mmol) at ambient temperature. The color of the solution changed to red immediately and after stirring for 5 h, the solution was filtered to remove suspended particles. Red single crystals of the title compound suitable for single crystal X-ray determination were obtained by slow diffusion of diethylether into the filtrate over a period of one week.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
