| 摘 要： | 用具有低自旋d^6构型的[(NH3)5MIm]^2^+, [(en)2Co(Im)2]^+(M=Co, Rh; Im^-为咪唑基)为配体与配位未饱和的含Cu单核配合物作用, 定向合成了八种新的咪唑桥联含Cu异双核、异三核和异五核配合物。对它们进行了元素分析、差热失重分析、摩尔电导测定及反射光谱研究, 确证了配合物的组成及分子中咪唑桥的存在, 通过对各配合物的ESR谱测定, 得到了它们的自旋Hamilton参数和键参数, 讨论了配合物的成键性质。

| Abstract: | Eight imidazolate (Im)-bridged heteronuclear complexes containing Cu2+ were prepared For these prepns., the kinetically inert, low spin d2 complexes, [(NH3)5CoIm]2+, [(NH3)5RhIm]2+, and [(en)2Co(Im)2]+ react as ligands with mononuclear Cu2+ complexes. By elemental anal., molar conductivity, TGA, DSC, and reflectance spectroscopy, all bridged heteronuclear complexes were characterized. Imidazolate bridges exist in the heteronuclear complexes. From the ESR spectra of the bridged heteronuclear complexes in solution, the bond parameters of Cu2+ were calculated and nature of the bond discussed. |
