Polymeric aqua(nitrilotriacetato)erbium(III)

Abstract

In the structure of the title compound, [Er(C(6)H(6)NO(6))(H(2)O)](n), the Er atoms are eight-coordinated by one N atom and six O atoms from three symmetry-related nitrilotriacetate (NTA) ligands, and by one O atom of a water molecule, adopting a distorted square-antiprismatic geometry. The Er atoms are linked by the NTA ligands into layers, which are interconnected via O-H.O hydrogen bonds between the water molecules and the carboxylate O atoms. The asymmetric unit contains one Er atom, one NTA ligand and one water molecule, all of which are located in general positions.
