平衡移动法测定β型钪-间硝基偶氮氯膦配合物真实组成和稳定常数的研究
Mobile Equilibrium Method for Determination of the True Composition and Stability Constant of β-type Complex of Scandium with Chlorophosphonazo-mN
【摘要】 本文以适用于MmRn型配合物的平衡移动法公式测定α型和β型钪与间硝基偶氮氯膦配合物的组成和稳定常数。结果表明,α型为单核配合物Sc(CPAmN)2,β型为多核配合物Sc2(CPAmN)6,其表观稳定常数依次为lgβ ′n=11.7和lgβ ′n=38.6。
【Abstract】 The true compositions and stability constants of α|type and β-type complexes of scandium with chlorophosphonazo-mN are determined by mobile equilibrium method. The results show that α-type complex is mononuclear (Sc(CPAmN)2) and β-type complex is polynuclear (Sc2(CPAmN)6) and their apparent stability constants are lgβ′n=11.7 and lgβ′n=38.6, respectively.
