| 摘要: 设计并合成了2种新型的salamo型N2O4配体的四核过渡金属配合物：[Ni2（L）（μ-OAc）（CH3OH）]2·4CH3OH（1）和[Zn2（L）（μ-OAc）（CH3CH2OH）]2（2）（H3L=6-hydroxy-6'-methoxy-2，2'-（ethylenediyldioxybis（nitrilomethylidyne））diphenol），并用元素分析、红外光谱、紫外-可见光谱、荧光光谱、Hirshfeld表面分析和单晶X射线晶体学对配合物进行了表征。X射线晶体学分析表明，配合物1和2均为对称的四核配合物。配合物1中所有六配位的镍（Ⅱ）原子都形成了扭曲的八面体几何构型，而配合物2中的所有五配位的锌（Ⅱ）原子则形成了扭曲的四方锥和三角双锥几何构型。 | |

| Abstract: Two newly designed tetra-nuclear transition metal(Ⅱ) complexes,[Ni2(L)(μ-OAc)(CH3OH)]2·4CH3OH (1) and[Zn2(L)(μ-OAc)(CH3CH2OH)]2 (2), derived from an unsymmetrical salamo-like donors-N2O4 ligand (H3L=6-hydroxy-6'-methoxy-2,2'-(ethylenediyldioxybis(nitrilomethylidyne))diphenol) were synthesized and characterized by elemental analyses, infrared spectra, ultraviolet-visible spectra, fluorescence spectra, Hirshfeld surfaces analyses, and single crystal X-ray crystallography. X-ray crystallographic analyses show that complexes 1 and 2 are all symmetrical four-nuclear complexes. All hexa-coordinated nickel(Ⅱ) ions in complex 1 form distorted octahedral geometries, while all penta-coordinated zinc(Ⅱ) ions in complex 2 form twisted quadrangular pyramid and triangular biconical geometries. | |
