Poly[aqua[μ3-N′-(carboxymethyl)ethylenediamine-N,N,N′-triacetato]samarium(III)]
Abstract
In the title coordination polymer, [Sm(C10H13N2O8)(H2O)]n, each samarium(III) centre is nine-coordinated by six O and two N atoms from three N′-(carboxymethyl)ethylenediamine-N,N,N′-triacetate ligands and one O atom of a water molecule, forming polymeric chains running parallel to the a axis. The packing is governed by intermolecular O—H...O hydrogen-bonding interactions.
