Poly[μ-5-ammonioisophthalato-aqua-μ-oxalato-dysprosium(III)]

Abstract

The title complex, [Dy(C8H6NO4)(C2O4)(H2O)]n, is a dysprosium coordination polymer with mixed anions and was obtained under hydrothermal conditions. In the structure, the oxalate and 5-aminoisophthalate ligands link the dysprosium ions, building up a two-dimensional metal–organic framework parallel to the (10overline{1}) plane. These sheets are further connected through O—H...O, N—H...O and C—H...O hydrogen bonds, forming a three-dimensional supramolecular structure.
