The first lanthanide mixed sulfate-sulfite inorganic coordination polymer, poly[diaqua-μ(4)-sulfato-di-μ(4)-sulfito-didysprosium(III)], [Dy(2)(SO(3))(2)(SO(4))(H(2)O)(2)](n), has been obtained, in which both sulfate and sulfite groups originate from the disproportionation of S(2)O(3)(2-) under hydrothermal and weakly acidic conditions. The crystal structure of the title compound exhibits a three-dimensional framework. The Dy(III) ion is surrounded by eight O atoms from one water molecule and two sulfate and five sulfite groups. These DyO(8) polyhedra have two shared edges and form an infinite zigzag Dy-O chain. In the bc plane, neighbouring chains are integrated through SO(3) trigonal pyramids, forming a two-dimensional sheet. Along the a-axial direction, the sulfate group, with the central S atom lying on a twofold axis, links adjacent two-dimensional sheets via two S-O-Dy connections, thus generating the three-dimensional framework.
The combination of redox and acid sites in lanthanide sulfonate leads to a potentially multifunctional catalyst for oxidation reactions. The title lanthanide sulfonate compound, [Yb(6)(CH(2)O(6)S(2))(4)O(OH)(8)(H(2)O)(6)](n), exhibits a novel one-dimensional columnar structure along the a direction. In the building unit of the columnar oligomer, a face-capped lanthanide octahedron, viz. [Ln(6)(mu(6)-O)(mu(3)-OH)(8)](8+), is found with an interstitial mu(6)-oxide group lying on an inversion centre, reports of which are rare in the literature. Adjacent hexameric cations are connected via two pairs of O-S-O bridges, thus forming a neutral column. The three-dimensional network is stabilized by an intricate pattern of intercolumnar hydrogen bonds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
