中文摘要	hydrothermal reactions of zinc uranyl acetate and 1-hydroxyethylidenediphosphonic acid (h4l) with 1,10-phenanthroline (phen), 2,2'-bipyridine (bipy), 1h-benzo[d]imidazole (bi), or 1-phenyl-1h-imidazole (pi) resulted in the formation of four new zinc uranyl compounds, namely, [zn-2-(phen)(2)(uo2)(2)(l)(2)(h2o)(3)]center dot 3h(2)o (znup-1), zn-2(bipy)(2)(uo2)(2)(l)(2)(h2o)(2) (znup-2), (hbi)[zn-0.5(uo2)(2)(l)(h2l)(h2o)(3)]center dot 3h(2)o (znup-3), and (hpi)[zn-0.5(uo2)(2)(h2o),(l)(h2l)]center dot h2o (znup-4). these four structures all comprise uranyl diphosphonate layers formed by uo7 pentagonal bipyramids and po3c tetrahedra. such layers are further connected by zn-centered polyhedra by sharing oxygens from phosphonate groups. for znup-1 and znup-2, the zinc atoms are terminally coordinated by phen and bipy molecules, respectively, resulting in two-dimensional (2-d) hybrid materials. in znup-3 and znup-4, the uranyl phosphonate layers are joined together by zn-o polyhedra forming three-dimensional (3-d) frameworks. the structures of znup-3 and znup-4 contain large channels along the a-axis with apertures around 3.4 x 13.3 and 4.4 x 12.2 angstrom(2), respectively. protonated templates exist in the channels, filling the space and compensating the negative charge of the anionic frameworks. photo luminescent studies reveal that znup-1 and znup-2 exhibit the characteristic vibronically coupled charge-transfer based uo22+ emission.
