摘　　要：A new terbium(Ⅲ)complex Tb2(C15H11O3)6(2,2?-bipy)2 has been synthesized with 2-(4-methylbenzoyl)benzoic acid and 2,2?-bipy ligands.Crystal data for the complex:monoclinic,space group P21/n,a=14.9738(5),b=13.5469(4),c=23.0683(7)?,β=103.950(3)o,V=4541.4(3)?3,Dc=1.511 g/cm3,Z=2,μ(MoKα)=1.620 mm-1,F(000)=2088,the final R=0.0318 and wR=0.0727.The Tb(Ⅲ)ion is coordinated by eight atoms to give a distorted square antiprism coordination geometry.The complex shows three fluorescence emission bands arising from the transitions of Tb3+:5D4→7F6(490 nm),5D4→7F5(545 nm)and 5D4→7F4(584 nm).The complex exhibits antiferromagnetism in the temperature range of 300~2 K.Also reported are the thermal stability properties of the complex.
