Abstract top

In the title heteronuclear ZnII-LuIII complex (systematic name: {6,6'-dimethoxy-2,2'-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato-1[kappa]4O1,O1',O6,O6':2[kappa]4O1,N,N',O1'}(methanol-1[kappa]O)-[mu]-nitrato-1:2[kappa]2O:O'-dinitrato-1[kappa]4O,O'-lutetium(III)zinc(II)), [LuZn(C18H18N2O4)(NO3)3(CH4O)], with the hexadentate Schiff base compartmental ligand N,N'-bis(3-methoxysalicylidene)ethylenediamine, the Lu and Zn atoms are triply bridged by two phenolate O atoms provided by the Schiff base ligand and one nitrate ion. The five-coordinated Zn is in a square-pyramidal geometry with the donor centers of two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms. The LuIII center has a tenfold coordination environment of O atoms, involving the phenolate O atoms, two methoxy O atoms, one methanol O atom, and two O atoms from two nitrate ions and one from the bridging nitrate ion. Weak intermolecular C-H...O interactions generate a two-dimensional layer structure.

Comment top

The potential applications of trivalent lanthanide complexes as contrast agent for magnetic resonance imaging and stains for fluorescence imaging have prompted considerable interest in the preparation, magnetic and optical properties of 3 d-4f hetorometallic dinuclear complexes (Baggio et al., 2000; Caravan et al., 1999; Edder et al., 2000; Knoer et al., 2005). As part of our investigations into the structure and applications of 3 d-4f hetorometallic Schiff base complexes(Sui et al., 2006; Sui et al., 2007), we report here the synthesis and X-ray crystal structure analysis of the title complex, (I), a new ZnII—LuIII complex with salen-type Schiff base N,N'-bis(3-methoxysalicylidene) ethylenediamine(H2L).

Complex (I) crystallizes in the space group P21/n, with zinc and lutetium triply bridged by two phenolate O atoms provided by a salen-type Schiff base ligand and one nitrate. The inner salen-type cavity is occupied by zinc(II), while lutetium(III) is present in the open and larger portion of the dinucleating compartmental Schiff base ligand.

The LuIII center has a decacoordination environment of O atoms, involving the phenolate O atoms, two methoxy O atoms, one methanol O atom, two O atoms from two nitrates and one from the bridging nitrate. The five kinds of Lu—O bond distances are significantly different, the longest being the Lu—O(methoxy) separations and the shortest being the Lu—O(phenolate) and Lu—O6(bridging nitrate).

The ZnII is in a square-pyramidal geometry and is five-coordinated by two imine N atoms, two phenolate O atoms and one of the bridging nitrate O atoms. The Zn atom is 0.5813 (3)Å above the mean N2O2 plane with an average deviation from the plane of 0.0951 (4) Å, which construct the bottom of square-pyramid. The Zn—O7(bridging nitrate) separation is 2.001 (4)Å and the angles of this Zn—O vector with the Zn—N or Zn—O bonds lie between 103.1 (5)° and 115.7 (6)°, which suggesting that the ZnII is in a slightly distorted square-pyramidal conformation.

Adjacent molecules are held together by weak interactions (C10—H10···O12i=3.443 (7) and C12—H12···O9i=3.445 (8); symmetry codes: (i)1/2 + x, 1/2 - y, 1/2 + z). these link the molecules into a two-dimensional layer structure(Fig 2).

Experimental top

H2L was prepared by the 2:1 condensation of 3-methoxysalicylaldehyde and ethylenediamine in methanol. Complex (I) was obtained by the treatment of zinc(II) acetate dihydrate (0.188 g, 1 mmol) with H2L(0.328 g, 1 mmol) in methanol solution (80 ml) under reflux for 3 h and then for another 3 h after the addition of lutetium(III) nitrate hexahydrate(0.469 g, 1 mmol). The reaction mixture was cooled and the resulting precipitate was filtered off, washed with diethyl ether and dried in vacuo. Single crystals of (I) suitable for X-ray analysis were obtained by slow evaporation at room temperature of a methanol solution. Analysis calculated for C19H22LuN5O14Zn: C 29.08, H 2.83, Lu 22.30, N 8.92,Zn 8.33%; found: C 30.01, H 2.85, Lu 22.39, N 8.98, Zn 8.38%. IR(KBr, cm-1): 1640(C=N), 1386,1490(nitrate).

Refinement top

The H atoms were positioned geometrically and treated as riding on their parent atoms, with C—H distances of 0.97Å (methylene) and 0.96Å (methyl), and with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for other H atoms. The methyl group of methanol was constrainted as idealized non-rotating CH3 group. The hydroxyl H atom, H1, was located in a difference Fourier map and refined with the O1—H1 distance restrained to 0.9 Å

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.
