【摘要】 以2,2′-联吡啶-6,6′-二甲酸（6,6′-H₂bpdc）和硫酸镍为原料，用水热法合成了配合物[Ni（6,6′-bpdc）（H₂O）₂]，通过元素分析、X射线（粉末与单晶）衍射、红外光谱、热分析和荧光光谱对[Ni（6,6′-bpdc）（H₂O）₂]进行了表征，并对X射线粉末衍射数据进行了计算。配合物[Ni（6,6′-bpdc）（H₂O）₂]的晶体结构属于三斜晶系，■空间群，晶胞参数为a=0.716 72（5）nm、b=0.802 52（5）nm、c=1.094 98（7）nm、α=92.214（2）°、β=96.290（2）°、γ=92.010（2）°，中心Ni ²⁺与配体6,6′-H₂bpdc中的N、O原子及两个配位水中的O原子配位，形成配位数为6的扭曲八面体构型。荧光性能研究表明6,6′-H₂bpdc配体与Ni ²⁺形成配合物[Ni（6,6′-bpdc）-（H₂O）₂]后产生了荧光猝灭现象。更多还原

【Abstract】 Complex[Ni（6,6′-bpdc）（H₂O）₂]was synthesized with 2,2′-bipyridine-6,6′-dicarboxylic acid（6,6′-H₂bpdc）and nickel sulfate hexahydrate as raw materials via hydrothermal method.The complex was characterized by elemental analyses,X-ray diffraction,infrared spectroscopy,thermogravimetric analysis and fluorescence,and X-ray powder diffraction data were indexed.The crystal structure of complex belongs to triclinic system with ■space group.The lattice parameters are a=0.716 72（5）nm,b=0.802 52（5）nm,c=1.094 98（7）nm,α=92.214（2）°，β=96.290（2）°andγ=92.010（2）°．The nickel ion is coordinated by oxygen and nitrogen atoms in the ligand and oxygen atoms in two coordinated water molecules to form the warped octahedral complex with a coordination number of 6.Fluorescence measurements showed that the ligand was coordinated with nickel ion to form the complex,resulting in fluorescence quenching.更多还原
