| 摘要: 以同物质的量比例的4-二苯基乙酸(Hbpa)、1,3-二(4-吡啶基)丙烷(bpp)和[Ag(NH3)](OH),在不同反应条件下制备了2个基于柔性配体的类三明治配合物{[Ag2(bpa)2(bpp)2]·2H2O}n(1)和{[Ag(bpa)(bpp)]·2H2O}n(2),对其进行了单晶结构、元素分析、红外光谱、荧光光谱和粉末衍射表征。结构表明1是由T型配位的银离子和Ag…Ag超分子作用组装而成的二维配合物;配合物2则是由四面体构型银离子和π…π堆积作用组装的二维配位超分子。此外,1和2还可在可见光区的不同位置发射较强荧光。 |

| Abstract: Two sandwich-like coordination polymers based on Ag(Ⅰ) and mixed flexible ligands, {[Ag2(bpa)2(bpp)2]·2H2O}n (1) and {[Ag(bpa)(bpp)]·2H2O}n (2) (bpa-=4-biphenylacetate, bpp=1,3-bis(4-pyridyl)propane), have been synthesized by solution reactions of Hbpa, bpp and [Ag(NH3)](OH) with the same ratio under different experimental conditions. They were characterized by single-crystal X-ray diffraction, EA, IRand XRD. Complex 1 is a two-dimensional network based on T-shaped coordination Ag(Ⅰ) ions and Ag…Ag interactions. In 2, the distorted tetrahedral coordination Ag(Ⅰ) ions are further organized by π…π stacking interactions into another two-dimensional network. 1 and 2 exhibit different and intense emissions in the visible region.
