以手性配体(+)-N-对甲苯磺酰-L-谷氨酸(H2tsgluO)和1,3-联(4-吡啶基)丙烷(bpp)与银盐反应合成了一种同手性的配合物{Ag(HtsgluO)(bpp)}n(1),对其进行了表征。X-射线单晶衍射测定表明,该配合物属单斜晶系,P21空间群,a=1.220 79(18)nm,b=1.034 49(16)nm,c=2.059 5(3)nm,β=96.006(2)°,V=2.586 7(7)nm3,Z=4,R1=0.060 2,银离子处于扭曲的四面体配位环境中,分别和1个HtsgluO-氧原子,2个bpp氮原子以及1个银离子配位。配合物通过银银键构成了二维层状结构,并且进一步通过氢键构成了三维超分子结构。此外,对配合物的热重和荧光性质进行了研究。

A homochiral complex [Ag（HtsgluO）（bpp）]n（1） was synthesized and characterized by the reaction of chiral（＋）-N-Tosyl-L-glutamic acid（H2tsgluO） and 1,3-bis（4-pyridyl）propane（bpp） with silver salts.Single crystal X-ray diffraction analysis reveals that complex 1 crystallizes in the monoclinic space group P21,a=1.220 79（18） nm,b=1.034 49（16） nm,c=2.059 5（3） nm,β=96.006（2）°,V=2.586 7（7） nm3,Z=4,and final R=0.060 2.The silver atom lies in a distorted tetrahedral environment formed by one HtsgluO-oxygen,two bpp nitrogen and one symmetry-related silver（Ⅰ） ions.It exhibits an infinite two-dimensional（2D） layered structure assembled by the argentophilic Ag-Ag interactions.Furthermore,these 2D layers are extended through extensive hydrogen bonding interactions to form an infinite 3D supramolecular network.In addition,the properties of thermogravimetric analysis and photoluminescent behavior of the complex have also been discussed.
