Synthesis, Crystal Structure and Properties of Cuprum-uranium Heterometallic Organic Coordination Polymer

在水热条件下,研究了以对苯二甲酸为主配体,邻菲啰啉为辅助配体与碘化亚铜和硝酸双氧铀反应,成功地合成了一例新的异金属铜-铀有机配位聚合物,也即{[Cu(phen)_2I]_2[(UO_2)_2(BDC)_3]·3H_2O}n(1),利用单晶X-射线衍射方法、红外光谱对该配位聚合物结构进行了基本表征。配合物1是由两个金属配合物阳离子客体[Cu(phen)2I]nn+、二维蜂窝状平面结构的聚阴离子主体框架[(UO_2)_2(BDC)_3]_n^(2n-)之间通过O-H···O氢键的相互作用形成三维超分子结构。此外,测试了配位聚合物1的固体紫外吸收光谱和研究了配合物的固体荧光性能。

A new cuprum-uranium heterometallic organic coordination polymer was obtained under hydrothermal method by using uranyl nitrate, cuprous iodide, benzene-1,4-dicarboxylate and phenanthroline. Namely {[Cu（phen）2I]2[（UO2）2（BDC）3]·3H2O}n（1）.The characterization of the coordination polymer was carried out by single-crystal X-ray diffraction, IR spectroscopy. Two metal complexes cationic objects [Cu（phen）2 I]nn＋, 2-D honeycomb flat structure of polyanion main body framework [（UO2）2（BDC）3]n^2n- n-via the O-H···O hydrogen bonding interactions to form 3-D supramolecular network. In addition,the UV-Vis absorption spectra of 1 was measured at room temperature and the solid fluorescent property was studied at room temperature.
