DSD Cd(Ⅱ)配合物的合成及晶体结构

Synthesis and Crystal Structure of the DSD and Cd(Ⅱ) Compound

为了探索氢键对配合物的影响,本文以4,4'-二氨基二苯乙烯-2,2'-二磺酸(简称DSD酸),邻菲啰啉(简称phen)和Cd(II)离子进行混配,合成了一个新型配合物,即[Cd(phen)2(DSD).1.5H2O]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.一维链之间又通过分子间强氢键N-H…O形成二维结构和三维结构,氢键对形成三维超分子结构起着非常重要的作用.

In order to probe the affect of hydrogen bonding interaction on the coordination compound,4,4′-Diaminostilbene-2,2′-Disulfonic Acid（DSD acid） were selected to coordinate with Cd（OAc）2·2H2O and 1,10 phenanthroline（phen）,and a novel compound [Cd（phen）2（DSD）1.5H2O] was obtained and structurally characterized by IR,elemental analyses and single crystal XRD respectively.The results obtained showed that the compound possesses 1-D structure,which is further connected into 2D and 3D framework by intermolecular hydrogen bonds.These hydrogen bonds are very important to form 3D structure.
