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 complexes [Ag2 (L) 2] (CF3COO) 2 (1) and [Ag2 (L) 2] (CF3SO3) 2 (2) [L = 2-methyl-4,6 - bis (3-pyridyl) pyrimidine] was synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction. The results of crystal structure analysis show that complexes 1 and 2 with double nuclei macrocyclic structure are connected by Ag (Ⅰ) ... Ag (Ⅰ) to form a one-dimensional chain structure and form a two-dimensional layered structure through π-π interaction structure. The fluorescence properties of complex 2 were studied.
