Rare earth ion center in distorted square anti-prism coordination environment: A novel three-dimensional coordination polymer with channels
The hydrothermal synthesis and the structure of the coordination polymer [La-2(ATPT)(3)(.)(H2O)(5)] (H2O)(2) (ATPT = 2-aminoterephthalic acid) were reported. The Rare-earth ion center was in the distorted square anti-prism coordination environment. These carboxyl groups linking La3+ ion centers engendered one-dimension channels with pending groups. Guest water molecules in these channels joined these pending groups via hydrogen bond.
