The templated synthesis of a unique type of tetra-nuclear uranyl-mediated two-fold interpenetrating uranyl-organic framework

Two novel tetra-nuclear uranyl-mediated two-fold interpenetrating networks, [U4O10(dbsf)(3)](2)[H(2)bpp](2) and [U4O10(dbsf)(3)][H(2)bpp], have been hydrothermally synthesized from a semi-rigid carboxylic acid, H(2)dbsf, with the organic base, bpp, as the charge balancing agent and stacking template (H(2)dbsf = 4,4'-dicarboxybiphenyl sulfone, bpp = 1,3-di(4-pyridyl) propane).
