Poly[[triaquasesqui-₂-oxalato-terbium(III)] methanol solvate]

Z. Rong-Hua and L. Han-Guo

Abstract: In the title complex, {[Tb(C₂O₄)_1.5(H₂O)₃]·CH₃OH}_n, each Tb^III atom is coordinated by six O atoms from three oxalate ligands and three water molecules, and displays a tricapped-trigonal prismatic geometry. The oxalate groups link the metal ions, forming layers perpendicular to the c axis that can be described via topological analysis as a three-connected (6³) sheet. O-HO hydrogen bonds from the water and methanol molecules to the oxalate ions further interconnect the layers, forming a supramolecular network.
