摘要: α,l-2,3,5,6-四氢-6-苯基咪唑[2,1-b]噻唑(以下简称四咪噻唑)与金属离子的络合物报导较少。我们应用pH法研究了四咪噻唑与稀土离子La3+,Pr3+,Nd3+,Sm3+,Eu3+,Gd3+和Yb3+的络离子。试验方法和数据处理按陈荣悌和徐光宪的方法;细节如前文。

Abstract: The stability of complex compounds formed by 2, 3, 5, 6-tetrahydro-6-phenylimidazo (2, 1-b) thiazole with La3+, Pr3+, Nd3+, Sm3+,Eu3+, Gd3+ and Yb3+ has been determined by pHmethod.The logarithm of the first consecutive stability constants (β1) of LaL3+, PrL3+, NdL3+, SmL3+ and EuL3+ could be expressed as linear function of the reciprocal of their ion radius (1/r).
