Tetrakis([mu]-2,4-difluorobenzoato)bis[(2,2'-bipyridine)(2,4-difluorobenzoato)terbium(III)]

Abstract top

In the centrosymmetric dinuclear title compound, [Tb2(C7H3F2O2)6(C10H8N2)2], the TbIII ion is coordinated by an N,N'-bidentate 2,2'-bipyridine molecule, and two O,O'-bidentate 2,4-difluorobenzoate (dfb) anions. One of the latter also bonds to the second TbIII centre through one of its O atoms. The third dfb anion bonds to one Tb atom from each of its O atoms. Thus, the three dfb species have three different coordination modes. This results in an irregular TbN2O7 coordination sphere for the metal ion. The F atoms and their associated H atoms in the simple bidentate dfb anion are disordered over two sets of sites in a 0.672 (10):0.328 (10) ratio.

Comment top

In recent years, carboxylic acids have been widely used as polydentate ligands, which can coordinate to transition or rare earth ions yielding complexes with interesting biological properties (e.g. Serre et al., 2005). Herein, we report the synthesis and X-ray crystal structure analysis of the centrosymetric title compound, (I), Fig. 1.

The TbIII is chelated by two 2,4-difluorobezoate anions and one 4,4'-bipyridine molecule. Two cations are linked into dimer via three bridging carboxylate groups from three 2,4-difluorobezoic acid. As a result, the TbIII ion is nine-coordinated with seven O atoms and two N atoms (Table 1).

Experimental top

A mixture of terbium(III) chloride (0.5 mmol), 2,4-difluorobezoic acid (1 mmol), sodium hydroxide (1 mmol), 4,4'-bipyridine (0.5 mmol), H2O (8 ml) and ethanol (8 ml) in a 25 ml Teflon-lined stainless steel autoclave was kept at 433 K for three days. Colourless blocks of (I) were obtained after cooling to room temperature with a yield of 16%. Anal. Calc. for C62H34F12Tb2N4O12: C 47.41, H 2.17, N 3.57%; Found: C 47.38, H 2.19, N 3.55%.

Refinement top

The H atoms were placed in calculated positions (C—H = 0.93 Å) and refined as riding with Uiso(H) = 1.2Ueq(C). The F atoms of the bidenate dfb anion are disordered over two sets of sites in a 0.672 (10):0.328 (10) ratio.

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.
