摘要
A new terbium(Ⅲ) complex Tb2(C15H11O3)6(phen)2 has been synthesized with 2-(4-methylbenzoyl)benzoic acid and 1,10-phenanthroline as ligands.Crystal data for the complex are as follows:monoclinic,space group P21/n,a=15.0786(6),b=13.5762(5),c=22.9683(9) A,β=104.130(4)°,V=4559.6(3) A3,Dc=1.540g/cm3,Z=2,μ(MoKα)=1.615 mm-1,F(000)=2136,the final R=0.0528 and wR=0.0740.The Tb(Ⅲ) ion is coordinated by eight atoms to give a distorted square antiprism coordination geometry.The complex shows four fluorescence emission bands arising from the transitions of Tb3+5D4→7F6(490 nm),5D4→7F5(546 nm),5D4→7F4(588 nm) and 5D4→7F3(622 nm).The complex is an antiferromagnet in the range of 300~2 K.Also reported in the paper is the thermal stability property of the title complex.
