Poly[hydronium [dysprosium(III)-₃-(ethylenediaminetetraacetato-⁸N,N',O,O',O'',O''':O'''':O''''')] monohydrate]

Abstract: The Dy^III atom in the title compound, (H₃O)[Dy(C₁₀H₁₂N₂O₈)]·H₂O, is N,N',O,O',O'',O'''-chelated by the edta tetraanion; it is also linked to the O atoms of two other tetraaanions in the polyanionic layer. The metal atom (site symmetry m) exists in a square-antiprismatic DyO₆N₂ geometry. The tetraanion is disordered over a mirror plane. The oxonium cation and water molecule are disordered, in a 2:1 ratio, and these occupy the space between adjacent layers. They probably interact with the layers by way of O-HO hydrogen bonds, but the H atoms could not be located.
