摘要
A new europium(Ⅲ) complex Eu2(C15H11O3)6(C12H8N2)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 = 15.1238(5), b = 13.5928(4), c = 22.9840(7) ?, β = 104.132(3)o, V = 4582.0(2) ?3, Dc = 1.522 g/cm3, Z = 4, μ(Mo Kα) = 1.433 mm-1, F(000) = 2128, the final R = 0.0447 and wR = 0.0826. The Eu(Ⅲ) ion is coordinated by eight atoms to give a distorted square antiprism coordination geometry. The complex shows two intense fluorescence emission bands arising from the transitions of Eu3+: 5 D0 → 7 F1(594 nm) and 5 D0 → 7 F2(617 nm). The complex is an antiferromagnetism system in the range of 150~300 K. Also reported in the paper is the thermal stability property of the title complex.
