合成了一种一维链状银配位聚合物[Ag(2,3-L)(NO3)(pph3)]n{2,3-L=N-[(2-吡啶基)甲基]-3-吡啶胺,pph3=三苯基膦},并且对其进行了元素分析、红外、热重、荧光、粉末及单晶X射线衍射等表征。标题化合物属于正交晶系,Pbca空间群,a=1.72479(5)nm,b=1.45923(4)nm,c=2.11904(6)nm,V=5.3333(2)nm3,Z=8,R=0.0336。每个Ag(I)离子分别与两个2,3-L配体中的两个氮原子,硝酸根中的一个氧原子和pph3中的一个磷原子配位,构筑了四配位扭曲的四面体构型,由于配体的桥联作用使得标题配合物沿b方向形成了一维链状结构,同时该配合物在室温下于372nm处表现出较强的荧光发射。
A novel one-dimensional chain-like silver coordination polymer [Ag (2,3-L) (NO3) (pph3)] n {2,3- L = N- [(2-pyridyl) methyl] Pyridinamine, pph3 = triphenylphosphine}, and characterized by elemental analysis, IR, TG, fluorescence, powder and single crystal X-ray diffraction. The title compound belongs to the orthorhombic system with Pbca space group, a = 1.72479 (5) nm, b = 1.45923 4 nm, c = 2.11904 6 nm, V = 5.3333 nm 2, 0.0336. Each Ag (I) ion coordinates with two nitrogen atoms in two 2,3-L ligands, one oxygen atom in nitrate and one phosphorus atom in pph3 respectively to form four-coordinate distorted tetrahedron Due to the bridging effect of the ligand, the title complex formed a one-dimensional chain structure along the b direction. At the same time, the complex showed strong fluorescence emission at 372 nm at room temperature.
