摘要：

A new dinuclear complex [Tb-2(BA)(6)(2,2'-bipy)(2)] (BA=4-(trifluoromethyl)benzoic acid, 2,2'-bipy=2,2'-bipyridine) has been synthesized. The complex was characterized by X-ray single-crystal structure analysis. The complex is a dimer with an inversion center. In the complex, two Tb3+ ions are linked by four carboxylate groups of BA ligands in bridging-bidentate coordination mode. Each Tb3+ ion is eight-coordinated with two nitrogen atoms from one 2,2'-bipy molecule, four oxygen atoms from four bridging-bidentate BA ligands and two oxygen atoms from one chelating-bidentate BA ligand. Intermolecular hydrogen bonds are formed in the crystal. The complex exhibits strong green fluorescence under ultraviolet light and the fluorescence spectrum consists of four lines peaking at 489, 545, 584 and 620 nm, which are corresponding to the D-s(4) -> F-7(j) (j=6 similar to 3) transitions of Tb3+ ion, respectively. CCDC: 727763.
