| Abstract: | A novel coordination polymer [Eu2(C6H8O4)3(H2O)2]n·n(4,4’-bpy) (Mr = 928.51) was synthesized by the hydrothermal reaction of EuCl3·6H2O, adipic acid and 4,4’-bpy, and determined by elemental analysis, IR spectroscopy, thermal gravimetric analysis, single-crystal diffraction and fluorescence property. X-ray analysis reveals that a three-dimensional network has been formed between Eu3+ by carboxyl of adipic acid. The crystal is of orthorhombic, space group Pbcn with a = 21.870(7), b = 7.652(2), c = 19.624(6) (A), V = 3284.1(17)(A)3, Z = 4, Dc = 1.878 g/cm3, μ = 3.854 mm-1, F(000) = 1824, R = 0.0345 and wR = 0.0565. The coordination polymer exhibits intensive red light under UV excitation at room temperature, which is attributed to the 5D0→7F2 transition of Eu(Ⅲ) ions. |
