摘要

A three-dimensional coordination polymer {[Dy（H2btec）2/4（btec）3/6（H2O）]·2H2O} n has been synthesized through the reaction of DyCl3·6H2O and 1,2,4,5-benzenetetracarboxylic acid by solvothermal technique, and the crystal structure was determined by X-ray diffraction. The Dy（Ⅲ） coordination polymer crystallizes in monoclinic, space group P21/n with a=10.7063（1）, b=7.1491（1）, c=17.1197（3）, α=90, β=97.10, γ=90°, V=1300.31（3）3 , C10H9DyO11 , Dc=2.389g/cm3 , Z=4, F（000）=892, the final R=0.0165 and wR=0.0448 for I 〉 2σ（I）. The title coordination polymer possesses a three-dimensional framework consisting of nine-coordinate Dy（Ⅲ） centers and two kinds of coordination modes for the 1,2,4,5-benzenetetracarboxylic acid ligands. Every btec4- ligand （deprotonated four protons from 1,2,4,5-benzenetetracarboxylic acid） in the title coordination polymer can clamp three Dy atoms like forceps, which could make the Dy atoms closer in the area of metal-metal interaction. The 3-D framework of the coordination polymer has many channels occupied by the free guest water molecules, and the hydrogen bonds between the coordinated carboxylic groups and guest water molecules could stabilize the crystal structure of the title coordination polymer. In addition, the luminescence properties were also studied.
