英文摘要	The reaction of uranyl nitrate with terephthalic acid (h2tp) under hydrothermal conditions in the presence of an organic base, 1,3-(4,4'-bispyridyl)propane (bpp) or 4,4'-bipyridine (bpy), provided four uranyl terephthalate compounds with different entangled structures by a ph-tuning method. [uo2(tp)(1.5)](h2bpp)(0.5)center dot 2h(2)o (1) obtained in a relatively acidic solution (final aqueous ph, 4.28) crystallizes in the form of a noninterpenetrated honeycomb-like two-dimensional network structure. an elevation of the solution ph (final ph, 5.21) promotes the formation of a dimeric uranyl-mediated polycatenated framework, [(uo2)(2)(mu-oh)(2)(tp)(2)](2)(h2bpp)(2)center dot 4.5h(2)o (2). another new polycatenated framework with a monomeric uranyl unit, [(uo2)(2)(tp)(3)](h2bpp) (3), begins to emerge as a minor accompanying product of 2 when the ph is increased up to 6.61, and turns out to be a significant product at ph 7.00. when more rigid but small-size bpy molecules replace bpp molecules, [uo2(tp)(1.5)](h2bpp)(0.5) (4) with a polycatenated framework similar to 3 was obtained in a relatively acidic solution (final ph, 4.81). the successful preparation of 2-4 represents the first report of uranyl organic polycatenated frameworks derived from a simple h2tp linker. a direct comparison between these polycatenated frameworks and previously reported uranyl terephthalate compounds suggests that the template and cavity-filling effects of organic bases (such as bpp or bpy), in combination with specific hydrothermal conditions, promote the formation of uranyl terephthalate polycatenated frameworks.
