合成了一个新颖的席夫碱N,O-双管能团有机配体(4-(吡啶基-2-亚甲基氨基)苯甲酸,4,2-pmabaH)(1),并在水和乙醇体系中合成了它的镉配合物[Cd(4,2-pmaba)(H2O)3](4,2-pmaba).H2O(2)。利用元素分析及X-射线单晶结构测定对其进行了表征。标题化合物1属于正交晶系,Pna21空间群。化合物2属于正交晶系,Pbcn空间群。在化合物2中,Cd(Ⅱ)的配位环境为七配位。其中有2种不同配位模式的配体,其M2L2环状结构单元通过氢键作用连接成一个具有三维结构的超分子化合物。对化合物1,2的荧光性质也进行了测定。
A novel Schiff base N, O-bi-functional organic ligand (4- (pyridyl-2-methyleneamino) benzoic acid, 4,2-pmabaH) Cd (4,2-pmaba) (H2O) 3] (4,2-pmaba) .H2O (2) was synthesized in ethanol system. It was characterized by elemental analysis and X-ray single crystal structure determination. The title compound 1 belongs to the orthorhombic, Pna21 space group. Compound 2 belongs to orthorhombic, Pbcn space group. In compound 2, the coordination environment of Cd (Ⅱ) is seven coordination. Among them, there are two kinds of ligands with different coordination modes. The M2L2 ring structure units are connected by hydrogen bonding to form a three-dimensional supramolecular compound. The fluorescence properties of Compounds 1 and 2 were also determined.
