两个含3,3'-硫代二丙酸配体的锰和铜配合物的合成、晶体结构与性质

摘要

A Mn(Ⅱ) coordination polymer,{[Mn(DPA)(4,4'-bipy)]· H2O}n (1) was prepared with 3,3'-thiodipropionic acid (DPA),4,4'-bipyridine (4,4'-bipy) and Mn(NO3)2 ·4H2O by hydrothermal method,and a Cu(Ⅱ) coordination polymer,{[Cu(DPA)(bpp)(H2O)]· H2O}n (2) was hydrothermal synthesized by using 3,3'-thiodipropionic acid (DPA),1,3-bis(4-pyridyl)propane (bpp) and Cu(NO3)2·3H2O.The coordination polymers were characterized by elemental analysis,thermal analysis,IR,XRD and X-ray single crystal diffraction.Complexes 1 and 2 have two-dimensional layer structures,Furthermore,there are hydrogen bonds and π-π stacking interactions contributing threedimensional supramolecular structures of 1 and 2,respectively.CCDC:1841409,1;1545628,2.%使用3,3'-硫代二丙酸、4,4'-联吡啶和硝酸锰在水热条件下反应合成了1个锰配合物,即{[Mn(DPA)(4,4'-bipy)]·H2O}n(1)(DPA=3,3'-硫代二丙酸,4,4'-bipy=4,4'-联吡啶);然后又利用3,3'-硫代二丙酸、1,3-双(4-吡啶基)丙烷和硝酸铜在水热条件下反应合成了1个铜配合物,即{[Cu(DPA)(bpp)(H2O)]· H2O}n(2)(DPA=3,3'-硫代二丙酸,bpp=1,3-双(4-吡啶基)丙烷).并对它们分别进行了元素分析、红外光谱、热稳定性、X射线粉末衍射和X射线单晶衍射的表征.结果表明:配合物1和2分别由3,3'-硫代二丙酸配体和不同氮杂环分子以及金属离子构筑,形成了二维层状的结构.氢键和π-π作用进一步将二维结构拓展成三维超分子网络.
