用水热法合成了基于刚性不对称三氮唑衍生物配体H_2ptp(H_2ptp=4-(5-(1H-pyrazol-4-yl)-4H-1,2,4-triazol-3-yl)pvridine)的2个Cd(Ⅱ)配合物{[Cd_2(Hptp)_2(OAc)_2]·7H_2O}_n(1)和{[Cd(Hptp)Cl(H_2O)]·H_2O}_n(2),并通过元素分析、差热分析、粉末X射线衍射和单晶X射线衍射进行表征。配合物1具有一个梯状的一维结构,在π…π堆积作用下这些一维梯链形成了超分子二维平面。在氢键的连接作用下,客体水分子形成了独特的以双五元水簇为结构单元的水链,这些水链填充在相邻的二维平面之间并通过氢键把二维平面连接成了三维超分子网络。配合物2具有一个新型的二维双层结构,分子间氢键把这些二维平面连成了三维结构。另外,测试了2个配合物的荧光性质。
The ligands based on the rigid asymmetric triazole ligands H_2ptp (H_2ptp = 4- (5- (1H-pyrazol-4-yl) -4H-1,2,4- triazol-3-yl) pvridine ) Of Cd (Ⅱ) complexes {[Cd_2 (Hptp) _2 (OAc) _2] · 7H_2O} _n (1) and {[Cd (Hptp) Cl (H_2O)] · H_2O} _n Characterization was performed by elemental analysis, differential thermal analysis, powder X-ray diffraction and single crystal X-ray diffraction. Complex 1 has a ladder-like one-dimensional structure, and these one-dimensional ladder chains form a supramolecular two-dimensional plane under the π ... π stacking effect. Under the hydrogen bonding effect, the guest water molecules form a unique water chain with the double five-membered water cluster as the structural unit. The water chains are filled between adjacent two-dimensional planes and connect the two-dimensional planes through hydrogen bonding Became a three-dimensional supramolecular network. Complex 2 has a novel two-dimensional two-layer structure, intermolecular hydrogen bonding to these two-dimensional plane into a three-dimensional structure. In addition, the fluorescence properties of two complexes were tested.
