Coordination polymers of rare-earth elements with 2-aminoterephthalic acid

详细

Coordination polymers of REEs with 2-aminoterephthalic acid [Ln₂(C₈H₅NO₄)₃(H₂O)₅]_n · 2nH₂O (Ln = Eu, Gd, or Tb) and [Y₂(C₈H₅NO₄)₃(H₂O)₄]_n · 4nH₂O were prepared by hydrothermal synthesis. Studies of the thermal behavior of these coordination polymers have shown that the removal of the solvate and the coordinated water molecules occurs at heating to 250°C and dehydratation products are stable up to 400°C. Detailed studies of the magnetic behavior of Eu, Gd, and Tb polymers were performed.
