In the centrosymmetric title compound, [Gd2(C7H3F2O2)6(C10H8N2)2], the asymmetric unit comprises one cation chelated by two 2,5-difluoro­benzoate and one 2,2′-bipyridine. Two cations are linked into dimers via three bridging carboxyl­ate groups from three 2,5-difluoro­benzoic acid units. The GdIII ion is nine-coord­inated by seven O atoms and two N atoms.

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 properties that are useful in materials science (Church & Halvorson, 1959; Chung et al., 1971) and in biological systems (Okabe & Oya, 2000; Serre et al., 2005; Pocker & Fong, 1980; Scapin et al., 1997). Herein, we report the synthesis and X-ray crystal structure analysis of the title compound, hexa(2,5-difluorobenzoato) bis(2,2'-bipyridine) bisgadolinium(III).

The molecular structure of the title compound is shown in Fig.1, GdIII is chelated by two 2,5-difluorobenzoate and one 2,2'-bipyridine. Two cations are linked into a dimer via bridging carboxylate groups from four 2,5-difluorobenzoate ions. The GdIII ion is nine-coordinated with seven O atoms and two N atoms. The Gd—N and Gd—O bond lengths are in the range of 2.567 (4)–2.585 (5) Å and 2.364 (4)–2.495 (4) Å, respectively.

Experimental top

A mixture of gadolinium chloride (0.5 mmol), 2,5-difluorobenzoic acid (1 mmol), Sodium hydroxide(1 mmol), 2,2'-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. Colorless crystals were obtained after cooling to room temperature.

Refinement top

All H atoms on C atoms were generated geometrically and refined as riding atoms with C—H= 0.93Å and Uiso(H)= 1.2 times Ueq(C).

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.
