| 摘 要： | A tetranuclear erbium complex with pyridine-2,4,6-tricarboxylic acid(H3ptc), Er4(ptc)4(H2O)18]·6H2O(1), has been synthesized by hydrothermal method. The complex crystallizes in triclinic system, space group P1, with a = 7.620(2), b = 10.459(3), c = 17.418(5) ?, α = 92.351(5), β = 92.080(5), γ = 95.627(4)°, V = 1379.1(7) ?3 and Z = 2. One Er(III) cation is eight-coordinated and the other is nine-coordinated. The complex exhibits characteristic luminescence of erbium cation in near-infrared region upon the excitation of UV-rays. Furthermore, a three-dimensional supramolecular complex was formed by weak hydrogen bonds among the tetranuclear units.
