摘　　要：以席夫碱碳腙类配体H2L自组装合成了一个新的M4[2×2]四方格子状结构锌(Ⅱ)配合物[Zn4(HL)4](ClO4)4·2MeCN·2MeOH(H2L=1,5-bis(1-(pyridine-2-yl)ethylidene)carbonhydrazide),并对其进行了元素分析、红外光谱、紫外可见光谱和X-射线单晶衍射法表征。单晶结构分析结果表明配合物中,Zn(Ⅱ)离子具有N4O2型扭曲的八面体配位构型,4个配体分别失去1个质子后以醇式与金属离子配位,由4个酚氧原子桥连4个Zn(Ⅱ)离子形成[2×2]格子状结构四核配合物。固态荧光测试表明配合物在530 nm附近有强的荧光发射峰。A novel tetranuclear M4[2x2] square grid complex [Zn4（HL）4]（CIOg）4·2MeCN .2MeOH （H2L=1,5-bis（1- （pyridine-2-yl）ethylidene）carbonhydrazide） was constructed via self-assembly using Schiff base ligand based on carbohydrazone derivative. The complex was characterized by elemental analyses, IR spectra, UV-Vis absorption spectra and single crystal X-ray diffraction. Single crystal structure analysis showed that all mental atoms have N402 distorted octahedral coordination spheres and four ligands are monodeprotonated with four enolyl oxygen atoms direct bridging the Zn ions to form a tetranuclear [2x2] square grid complex. Furthermore, the fluorescent spectra analysis indicated the tetranuclear Zn（II）4 complex exhibits intense fluorescence emission band at around 530 nm in the solid state. CCDC： 922042.
