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.展开更多
