A new europium(III) complex Eu(L)3(Phen)2(1) with 2-benzoylbenzoic acid(HL) and 1,10-phenanthroline(Phen) as ligands has been synthesized. Crystal data for the complex are as follows: monoclinic, space group P21/c, a = 2.2577(4), b = 1.23484(19), c = 1.8789(3) nm, β = 94.918(3)o, V = 5.2189(14) nm~3, Dc = 1.512 g/cm~3, Z = 4, μ(Mo Kα) = 1.269 mm~(-1), F(000) = 2408, the final R = 0.0433 and w R = 0.1038. The Eu(III) ion is coordinated by nine atoms to give a single-capped square antiprism coordination geometry. 1 shows two intense fluorescence emission bands arising from the transitions of Eu~(3+): ~5D_0→~7F_1(597 nm) and ~5D_0→~7F_2(615 nm) with an excitation wavelength of 396 nm. In addition, 1 displays antiferromagnetic property at low temperature.
