Two new tetranuclear cluster‐based compounds, namely [Cd2(L1)(H2O)(DMA)]n (1) and [Cd2Ba2(L2)(H2O)6(DMA)]n (2) [H4L1 = 3‐(3',5'‐dicarboxylphenoxy) phthalic acid, H4L2 = 6‐(3',4'‐dicarboxyl‐phenoxy) isophthalic acid, DMA = N,N'‐dimethylacetamide], were successfully synthesized under solvothermal conditions and structurally characterized by single‐crystal X‐ray diffraction analyses. Compound 1 features a two‐dimensional (2D) layered framework with tetranuclear [Cd4(COO)6] clusters as building subunits, and can be simplified into a binodal (3, 6)‐connected kgd topological network with the schläfli symbol of {43}2{46;66;83}, and compound 2 features a three‐dimensional (3D) complicated framework based on heterometallic tetranulear [Cd2Ba2(COO)8] cluster subunits, and can be simplified into a binodal (3, 6)‐connected topological network. In addition, compounds 1 and 2 not only have high thermal stabilities but also show strong luminescent emissions at room temperature.

基于同构半刚性四羧酸酯配体的两种新型基于四核簇的配位聚合物:合成,结构和发光性质

两种新的基于四核簇的化合物,即[Cd 2(L1)(H 2 O)(DMA)] n1)和[Cd 2 Ba 2(L2)(H 2 O)6(DMA)] n2)[H 4 L1 = 3-(3',5'-二羧基苯氧基)邻苯二甲酸,H 4 L2 = 6-(3',4'-二羧基苯氧基)邻苯二甲酸,DMA = N,N'-二甲基乙酰胺],在溶剂热条件下成功合成,并通过单晶X射线衍射分析对其结构进行了表征。化合物1的特征是具有四核[Cd 4的二维(2D)分层框架(COO)6 ]聚类为建筑物的子单元,并可以简化为具有{4 3 } 2 {4 6 ; 6 6 ; 8 3 }的schläfli符号的,与双脚架(3,6)连接的kgd拓扑网络2具有基于异金属四核[Cd 2 Ba 2(COO)8 ]簇子单元的三维(3D)复杂框架,并且可以简化为连接成双斜面(3,6)的拓扑网络。此外,化合物12 不仅具有高的热稳定性,而且在室温下也显示出强大的发光发射。
