摘　　要：在水热反应条件下成功地合成了3个4d-4f异金属化合物{[LnAg2（QA）4（H2O）5]（ClO4）}n（Ln=Nd（1）,Tb（2）,Eu（3）;HQA=3-喹啉羧酸）。用单晶衍射分析,元素分析和粉末衍射分析对晶体结构进行了表征。化合物1-3同构,在bc平面形成二维层结构,抗衡离子ClO4-与二维层通过氢键作用形成三维超分子结构。研究了配合物2和3的荧光性质。Three 4d-4f heterometallic coordination compounds, namely, {[LnAg_2（QA）_4（H_2O）_5]（ClO_4）}n（Ln =Nd（1）,Tb（2）, Eu（3）; HQA=3-quinolinecarboxylate acid）, were successfully synthesized under hydrothermal conditions.Compounds 1-3 are isostructural and feature 2D layer structures on bc plane, which are further connected by the counter anions ClO_4-by hydrogen bonds into 3D supermolecular structure. All these compounds are characterized by single-crystal X-ray diffraction, elemental analyses（EA） and powder X-ray diffraction（PXRD）. Furthermore,the thermal stabilities and fluorescent properties of the selected compounds have been investigated.
