以1,3-二(4′-羧基苯氧基)苯甲酸(H3L)为配体与金属盐反应,在水热条件下成功合成了2个金属-有机骨架(MOFs),分别为[Cd2(CH3COO)(L)(H2O)2]n(1)和[Na(H2L)]n(2)。由于H3L配体配位模式的不同,配合物表现出不同的网络结构。单晶结构分析表明,配合物1属于三斜晶系,P1空间群,配合物2属于单斜晶系,C2/c空间群。配合物1中Cd2+离子的次级构筑单元经由L3-连接形成三维网络结构。配合物2是一个5-连接的拓扑网络结构,其拓扑符号为(46·64)。此外,还对配合物1的荧光性能进行了分析。
Two metal-organic frameworks (MOFs) were successfully synthesized under hydrothermal conditions using 1,3-bis (4’-carboxyphenoxy) benzoic acid (H3L) (CH3COO) (L) (H2O) 2] n (1) and [Na (H2L)] n (2). Due to the different coordination modes of H3L ligands, the complexes showed different network structures. Single crystal structure analysis showed that complex 1 belonged to triclinic system, space group P1, and complex 2 belongs to monoclinic space group C2 / c. The secondary building blocks of Cd2 + ions in complex 1 formed a three-dimensional network structure via L3-linkage. Complex 2 is a 5-connected topological network structure with topological symbol (46.64). In addition, the fluorescence properties of complex 1 were also analyzed.
