为了探索π-π堆积作用和氢键对配合物的影响,本文以1,5-蒽醌二磺酸钠(简称Na2AQDS),2,2’—联吡啶(简称bipy)和Cd(II)离子进行混配,合成了一个新型配合物,即[Cd(bipy)2(AQDS)]n,并经元素分析、红外光谱和单晶X射线衍射进行了结构表征.X-ray晶体结构测定表明此配合物的基本结构是一维链状结构.一维链之间又通过π-π堆积作用和分子间氢键C-H…O形成二维结构和三维超分子结构.可见π-π堆积作用和氢键对形成三维超分子结构起着非常重要的作用.同时还对配合物进行了荧光及热重性质的研究.
In order to explore the effect of π-π stacking and the effect of hydrogen bonding on the complex, sodium 1,5-anthraquinone disulfonate (Na2AQDS), 2,2’-dipyridyl (bipy) and Cd (II) (Cd (bipy) 2 (AQDS)] n was synthesized and characterized by elemental analysis, IR and single crystal X-ray diffraction. The X-ray crystal structure determination showed that The basic structure of the complex is a one-dimensional chain structure, and the two-dimensional structure and the three-dimensional supramolecular structure are formed by π-π stacking and intermolecular hydrogen bonding CH ... O. It can be seen that π-π stacking and hydrogen The bond plays a very important role in the formation of three-dimensional supramolecular structures, and the fluorescence and thermogravimetric properties of the complexes have also been investigated.
