摘要： In the centrosymmetric dinuclear title compound, [Tb(2)(C(7)H(3)F(2)O(2))(6)(C(10)H(8)N(2))(2)], the Tb(III) 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 Tb(III) 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 TbN(2)O(7) 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.
