| 摘 要： | 本文用极谱法研究了以丁二酸(suc)为初级配体并分别以乙酸丙酮(acac)、氨基乙酸(gly)和乙二胺(en)为次级配体的Pb(Ⅱ)的1:1:1型混合配体化合物的稳定性,实验结果表明Pb(Ⅱ)-suc-acac体系的稳定性略低于统计效应的期望值,而其他两个体系则都高于期望值。对于统计效应的正偏离,按以下顺序增加,Pb-suc-acac

| Abstract: | The stabilities of 1:1:1 mixed ligand complexes of Pb(Ⅱ) with succinate(suc)as first ligand and acetylacetone(acac), glycine(glg) or ethylenediamine(en)as second ligand ate studiel by polarographical method. The stability constant of Pb(Ⅱ)-suc-acac system is slightly smaller than the value expected by statistical effect, but the others are larger than the expected values. The positive deviation from statistical effect is in the following order: Pb(Ⅱ)-suc-en>Pb(Ⅱ)-sue-gly>Pb(Ⅱ)-suc-acac. The reasons for the above order and stability of mixed ligand comPlex dependence on ligand are discussed |
