Poly[hydronium [dysprosium(III)-μ3-(ethylenediaminetetraacetato-κ8N,N′,O,O′,O′′,O′′′:O′′′':O′′′'')] monohydrate

Abstract

The DyIII 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—H⋯O hydrogen bonds, but the H atoms could not be located.
