Abstract

TTHA complexes with diamagnetic rare earth ions (La³⁺, Y³⁺ and Lu³⁺) were studied by ¹H and ¹³C NMR spectroscopy. A symmetric structural model was suggested for La(TTHA) complex and an asymmetric model for Y(TTHA) and Lu(TTHA) complexes. The complex formation was dependent on the pH value of the solution. The interactions of La(TTHA) with the additional metal ions (La³⁺, Y³⁺ and Ca²⁺) were relatively weak, but relatively strong for that of Lu(TTHA) with the additional Lu³⁺.
