Poly[aqua(μ5-2-oxido-4-sulfonatobenzoato)lanthanum(III)]

Abstract

The title compound, [La(C7H3O6S)(H2O)]n, forms a three-dimensional framework in which the asymmetric unit contains one LaIII atom, one 5-sulfosalicylate (2-oxido-4-sulfonatobenzoate) ligand and one coordinated water molecule. The LaIII atom is coordinated by nine O atoms from three carboxylate, three sulfonate and two hydroxyl groups, and one water molecule, forming a distorted trigonal-prismatic square-face tricapped geometry.
