摘 要: | The complex Eu(3-IBA)3·2,2'-bipy]2 was synthesized from 3-iodobenzoic acid (3-HIBA), 2,2'-bipyridine (2,2‘-bipy) and EuCl3·6H2O by hydrothermal synthesis, and its crystal structure was determined by X-ray single-crystal diffraction. It is of triclinic, space group Pi, with a = 10.958(2), b = 12.311(3), c = 12.556(3) A, α = 81.549(3), β = 82.404(4), γ = 78.348(3)°, Mr = 1049.15, V= 1631.7(6) A3, Z = 1, Dc = 2.135 g/cm^3, F(000) = 980, 2(MoKa) = 0.71073 A,μ(MoKa) = 4.804 mm^-1, the final R = 0.0329 and wR = 0.0723 for 4640 observed reflections with I 〉 2σ(I). The Eu(Ⅲ) ion is eight-coordinated and two Eu(Ⅲ) ions are held together by four 3-iodobenzoate groups in the bidentate bridging mode. The complex was characterized by DTA-TG, IR, UV and fluorescence spectra.
