摘要：

Three new 3D metal-organic frameworks (MOFs), namely scandium and yttrium naphthalenedisulfonates (nds), have been obtained and their crystal structures have been determined by single crystal X-ray diffraction. The 1,5- and 2,6-nds scandium compounds (RPF-12 and RPF-13, respectively), both with the formula [Sc-2(nds)(OH)(4)](n), and the yttrium naphthalenedisulfonate [Y(1,5-nds)(OH)(H2O)](n), RPF-14, were synthesised under hydrothermal conditions. The frameworks can be described as pillared layered motifs where sheets of sulfonate bridged polyhedra are connected by naphthalene units. The scandium disulfonate [Sc-2(2,6-nds)(OH)(4)](n) is the first obtained rare-earth 2,6-nds MOF with the same stoichiometry and arrangement as its 1,5-nds counterpart. The new MOFs, with high thermal stability, act as active and selective bifunctional heterogeneous catalysts in the epoxidation of linalool and oxidation of sulfides.
