摘要
为了探索氢键和π-π堆积作用对配合物的影响,本文以1,5-蒽醌二磺酸钠(简称Na2AQDS),1,10-菲啰啉(简称phen)和Co(II)离子进行混配,合成了一个新型配合物,即[Co(phen)_2(AQDS)(H_2O)],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单核结构.相邻的单核子单元通过分子间强氢键O-H…O形成一维链,进而又通过π-π堆积作用形成二维网络.可见氢键和π-π堆积作用对拓展配合物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 investigate the influence of hydrogen bonding interaction and π-π stacking interactions on the coordination compound,anthraquinone 1,5 disulfonic acid disodium salt( Na_2AQDS) was selected to coordinate with Co(OAc)_2·4H_2O and 1,10 phenanthroline( phen). A new compound [Co(phen)_2(AQDS)(H_2O)]was obtained and structurally characterized by IR,elemental analyses and single crystal XRD respectively. The results obtained show that the compound exhibits a six coordinated mono-nuclear structure,which is further joined together into a 1D chain by intermolecular hydrogen bonds. Also,2D framework was formed by π-π interactions. These interactions are very important to form the supramolecular structure. In addition,FL and TG properties are discussed in the article.
