含Zn咪唑桥联异多核配合物的合成与表征

Syntheses and Characterization of Imidazolate Bridged Heteropolynuclear Complexes Containing Zn

用具有低自旋d^B构型的[(NH_3)_5MIm]^(2+)(M=Co,Rh)和[(en)_2Co(Im)_2]^+为配体,与配位未饱和Zn的单核配合物作用,定向合成了5种新的含Zn咪唑桥联异双核、异三核配合物,并进行了元素分析、差热分析、摩尔电导及~1H NMR测定,确证了组成及咪唑桥的存在。

Five species of imidazolate bridged heteropolynuclear complexes containing Zn (Ⅱ ) were prepared. In the syntheses, the kinetically inert, low spin d6 complexes, [(NH3)5CoIm]2+, [(NH3)sRhIm]2+ and [(en)2Co(Im)2]+ were used as ligands to react with mononuclear Zn ( Ⅱ ) complexes. By elemental analysis, molar conductivity, TGA, DSC and 1H NMR study, all bridged heteropolynuclear complexes were characterized.
