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).
