Poly[[triaqua(₃-pyridine-2,4,6-tricarboxylato)gadolinium(III)] monohydrate]

H.-S. Wang and W.-Q. Zhang

Abstract: The title compound, {[Gd(C₈H₂NO₆)(H₂O)₃]·H₂O}_n, was obtained in water under hydrothermal conditions. The Gd^III ions are nine-coordinated by two O and one N atoms from one pyridine-2,4,6-tricarboxylate ligand, two O atoms from another ligand, one O atom from a third ligand and three coordinated water molecules. Each ligand binds three metal centers. Two-dimensional layers are formed through the Gd-O bonds and the layers are linked by O-HO hydrogen bonds, forming a three-dimensional network.
