In the title heteronuclear Zn^II—Tb^III complex (systematic name: {6,6′-dimethoxy-2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato-1κ⁴O⁶,O¹,O^1′,O^6′}:2κ⁴O¹,N,N′,O^1′-μ-nitrato-1:2κ²O:O′-dinitrato-1κ⁴O,O′-terbium(III)zinc(II)), [TbZn(C₁₈H₁₈N₂O₄)(NO₃)₃], with the hexadentate Schiff base compartmental ligand N,N′-bis(3-methoxysalicylidene)ethylenediamine (H₂L), the Tb and Zn atoms are triply bridged by two phenolate O atoms of the Schiff base ligand and one nitrate ion. The five-coordinate Zn atom 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 Tb^III center has a ninefold coordination environment of O atoms, involving the phenolate O atoms, two methoxy O atoms, 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 Zn^II—Tb^III 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 terbium triply bridged by two phenolate O atoms provided by the Schiff base ligand and one nitrate ion. The inner salen-type cavity is occupied by zinc(II), while terbium(III) is present in the open and larger portion of the dinucleating compartmental Schiff base ligand.

The Tb^III center has a ninefold coordination environment of O atoms, involving the phenolate O atoms, two methoxy O atoms, two O atoms from two nitrate ions and one from the bridging nitrate ion. The four kinds of Tb—O bond distances are significantly different, the longest being the Tb—O (methoxy) separations and the shortest being the Tb—O (phenolate) and Tb—O5 (bridging nitrate).

The Zn^II 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 0.6062 (4) Å above the mean N₂O₂ plane with an average deviation from the plane of 0.0383 (3) Å, which construct the bottom of square-pyramid. The Zn—O6 (bridging nitrate) separation is 1.978 (3)Å and the angles of this Zn—O vector with the Zn—N or Zn—O bonds lie between 102.5 (5)° and 112.7 (6)°, which suggesting that the Zn^II is in a slightly distorted square-pyramidal conformation.

Adjacent molecules are held together by weak interactions (C5—H5···O11ⁱ= 3.376 (5) Å and C9—H9A···O13ⁱⁱ= 3.487 (6) Å; symmetry codes: (i) 1/2 + x, 1/2 - y, -1/2 + z; (ii) 1 - x, -y, 1 - 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 terbium(III) nitrate hexahydrate (0.453 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 C₁₈H₁₈N₅O₁₃TbZn: C 29.35 H 2.46, N 9.51, Tb 21.57, Zn 8.88%; found: C 29.40, H 2.45, N 9.53, Tb 21.60, Zn 8.906%. IR (KBr, cm^-1): 1640 (C=N), 1386,1490(nitrate).

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.
