摘要 用分层法合成了两个配合物[Ag2(L)2](CF3COO)2(1)和[Ag2(L)2](CF3SO3)2(2)[L=2-甲基-4,6-二(3-吡啶基)嘧啶],并用元素分析、红外光谱、X-射线单晶衍射等手段对其进行了表征。晶体结构分析结果表明:具有双核大环结构的配合物1和2由Ag(Ⅰ)…Ag(Ⅰ)相互作用连接形成一维链状结构,并进一步通过π-π相互作用形成二维层状结构。研究了配合物2的荧光性质。 Two silver(I) complexes [Ag/(L)2](CF3COO)2 (1) and [Agz(L)/](CF3SO3)2 (2) [L=2-methyl-4,6-di(pyridin-3- yl)pyrimidine] were synthesized and characterized by elemental, IR and single crystal X-ray diffraction analyses. The binuclear complexes 1 and 2 form infinite 1D chains through argentophilic interactions, and further extend into 2D supramolecular networks by π-π interactions. The photoluminescent measurements reveal that complex 2 exhibits fluorescent emission in the solid state at room temperature and the luminescent decay time was determined. CCDC; 827908, 1; 827909, 2.
