摘　　要：本文研究了乙胺等四种正胺配体与Cu(ClO_4)_2的配位络合物溶液的低温(77K)ESR谱。用超精细耦合常数和g值计算了σ键强度以及配位场分裂能次序。结果表明:σ键强度随着配位胺分子碳链增长而增强,至正戊胺配位络合物开始减弱;在这些Cu(Ⅱ)-正胺络合物中氨基以与氨不同的键性和Cu(Ⅱ)离子键合。The ESR spectra of the complexes of four kinds of n-amine with Cu(ClO_4)_2 have beeninvestigated at 77K. The relative order of σbonding strength and ligand field splitting en-ergies have been calculated by using the hyperfine coupling constants and g values. The re-sults indicate that the σbonding strength increases with the lengthening of carbon chain inligand molecules and starts to decrease in the ligand complex of n-valeramine. The bondingnature of amino groups is different from those of ammonia in these copper (Ⅱ)-n-aminescomplexes.
