Poly[μ2-aqua-μ4-(2-{3-[(6-chloropyridin-3-yl)methyl]-2-oxoimidazolidin-1-yl}acetato)-sodium]

In the title compound, [Na(C11H11ClN3O3)(H2O)]n, there are two independent NaI ions, one of which lies on an inversion center and is coordinated in a slightly distorted octahedral environment. The other NaI ion lies on a twofold rotation axis and is cooordinated in a slightly distorted trigonal–bipyramidal coordination environment. In the organic ligand, the imidazolidine ring adopts a half-chair conformation. The NaI ions bridge organic ligands and water molecules, forming a two-dimensional structure parallel to (100). There are intermolecular O—H...O and weak C—H...O hydrogen bonds within the two-dimensional structure.
