中文摘要：

通过使用Schlenk技术将零维异双核[{LNi（MeOH）2}Gd（NO3）3]·2MeOH（H2L=N,N’-bis（2-hydroxy-3-methoxybenzylidene）-1）金属配合物与LiTCNQ（TCNQ=7,7,8,8-TetraCyanoquinodimethan）反应,合成了一种新的零维3d-4f希夫碱钆镍异四核配合物[Ni（MeO）Gd（NO3）2L]2,并采用元素分析、红外、热重及单晶X射线衍射等技术对其进行了表征。标题配合物中的钆镍四核金属亚单元通过氢键相连形成左手与右手的超分子螺旋链,不同手性的螺旋链通过共享钆离子而交替相连,并且构筑成一个消旋的二维交织螺旋层,该螺旋层最终凭借螺旋层与螺旋层间的π…π相互作用形成了三维的超分子网络结构。

英文摘要：

A new Schiff base, 3d-4f Gd^Ⅲ-Ni^Ⅱ, 0-D complex, [ Ni（MeO） Gd（ NO3） 2L] 2, was obtained from the [ { LNi （ MeOn）2 } Gd （ NO3 ） 3 ] · 2MeOH 0-D complex reacting with LiTCNQ by means of Schlenk technique. The complex was characterized by elemental analysis, IR, TGA and single crystal X- ray diffraction technique. In the complex, the tetranuclear metal subunits are linked together by H bond- ing to form supramolecular left- and right-handed helixes. Through sharing Gd ions, the helixes with different chirality are bridged to generate a 2-D interwined mesomeric layer. The helical layers are further connected by π…π interactions between the adjacent layers to form a 3-D supramolecular network.
