摘　　要：采用溶剂热法,8-羟基喹啉类配体与Zn Cl2组装得到一种新型的三核配合物1,并用元素分析,红外光谱,粉末和单晶X-射线衍射对配合物1进行表征。从X-射线单晶衍射分析可知配合物1是通过五个配体桥联而成的三核结构。采用荧光光谱研究了配合物1的固态荧光性质(荧光发射,荧光寿命和量子产率),结果表明配合物1在固体状态下发射黄色荧光。Using solvothermal method, a novel trinuclear complex, namely [Zn3CIL5] （1）, was fabricated by assembly of ZnCI2 salt with an 8-hydroxyquinolinate ligand HL. The complex was characterized by elemental analysis, IR spectroscopy, powder and single- crystal X-ray diffraction. X-ray structural analysis shows that 1 exhibits a trimeric core structure, which is bridged by five 8-hydroxy- quinolinate-based ligands. The luminescent properties （fluorescent emission, lifetime, and quantum yield） of I were investigated by photoluminescence （PL）, the results show that I emits yellow luminescence in the solid state.
