Preparation and properties of solid rare-earth Β-hydroxyethyliminodiacetates

  • 18 Accesses


  1. 1.

    The authors have synthesized for all the rare earths the hitherto undescribed solid mono-Β-hydroxyethyliminodiacetates of the composition LnZCl·4H2O.

  2. 2.

    They have subjected the LnZCl·4H2O to x-ray, thermogravimetric, and derivatographic analysis. They have investigated the IR spectra of the hydrates and anhydrous LnZCl, and their deuteroderivatives.

  3. 3.

    From the data obtained, they infer that LnZCl·4H2O are polymeric, and they also draw certain conclusions on the character of the bond of the Ln3+ ion with different donor groups of the ligand in these compounds.
