| 摘 要： | A binuclear terbium complex with 2,4,6-Trimethylbenzoate and 1,10-phenanthroline, [Tb2(TMBA)6(Phen)2], has been synthesized (TMBA=2,4,6-Trimethylbenzoic acid and phen=1,10-phenanthroline) and characterized by IR, elemental analysis and X-ray diffraction methods. The title complex crystallizes in monoclinic system, space group P21/c with a=1.327 5(2) nm, b=2.817 9(5) nm, c=1.282 5(2) nm, β=116.692(3)°, V=4.286 2(13) nm3, Z=4，Dc=1.423 g·cm-3. There are four bridged carboxylate groups of the 2,4,6-trimethylbenzoic acid bonded to the two terbium ions, each ions is also chelated with the two oxygen atoms of a molecule of the 2,4,6-trimethylbenzoic acid and the two nitrogen atoms of a 1,10-phenanthroline respectively, forming a 8-coordination distorted square antiprism. Average Tb-O and Tb-Ndistance of the two Tb(Ⅲ) ions are equal respectively. This shows the two terbium ions are in the same chemical enviorments. The complex emits intense green fluorescence under ultraviolet light. CCDC: 619215.
