利用水热法成功合成了一个新颖的稀土-过渡金属有机骨架Er(pyba)3(H2O)2CuI(Hpyba=4-吡啶-3-苯甲酸),并通过元素分析、红外光谱、X-射线粉末衍射、单晶X-射线衍射及热分析等对其进行了表征。结构分析表明:2种不同的{Er2}和{Cu2}单元经配体连接形成一维链,这些一维链通过氢键和π-π堆积作用进一步连接形成三维超分子网络。
A novel rare earth-transition metal organic framework Er (pyba) 3 (H2O) 2CuI (Hpyba = 4-pyridine-3-benzoic acid) was successfully synthesized by hydrothermal method and characterized by elemental analysis, IR, X-ray powder Diffraction, single crystal X-ray diffraction and thermal analysis of its characterization. Structural analysis shows that two kinds of {Er2} and {Cu2} units are connected by ligand to form a one-dimensional chain, and these one-dimensional chains are further connected by hydrogen bond and π-π stacking to form a three-dimensional supramolecular network.
