Summary: | The title compound, {[Er2(C4H2O4)2(C2O4)(H2O)4]·4H2O}n, was synthesized by the reaction of erbium nitrate hexahydrate with fumaric acid and oxalic acid under hydrothermal conditions. The Er3+ cation (site symmetry ..2) is eight-coordinated by six O atoms from four fumarate anions (site symmetry ..2) and one bidentate oxalate anion (site symmetry 222), and by two water molecules. The complex exhibits a three-dimensional structure consisting of oxalate pillared Er–fumarate layers with channels occupied by coordinating and lattice water molecules. The three-dimensional structure features by Owater—H...O hydrogen bonds involving both the coordinating and lattice water molecules. |
