Deskripsi
In the title coordination polymer, {[Eu(C7H2NO5)(H2O)3]·H2O}n, the EuIII atom is eight-coordinated by a tridentate 4-oxidopyridine-2,6-dicarboxylate (hpc) trianion, two monodentate hpc anions and three water molecules, forming a distorted bicapped trigonal–prismatic coordination geometry. The hpc ligands bridge adjacent EuIII ions, forming infinite double chains. Adjacent chains are further connected by hpc ligands into sheets. O—H...O hydrogen bonds then generate a three-dimensional supramolecular framework.
