资源简介：
The hydrothermal reaction of uranyl nitrate and 1,4-benzenebisphosphonic
acid in the presence of monovalent and divalent metal hydroxides results
in the formation of four new uranyl coordination polymers: Ag2{(UO2)[C6H4(PO3H)2]2} (AgUbbp), Cs{(UO2)[C6H4(PO3H0.5)2]} (CsUbbp), [Ba(H2O)3]{(UO2)3[C6H4(PO3)2]2(O)}·5(H2O) (BaUbbp), and [Sr(H2O)3]{(UO2)2[C6H4(PO3)2](OH)2(H2O)}·3(H2O) (SrUbbp). AgUbbp and CsUbbp complexes are constructed
from UO6 units with tetragonal bipyramidal coordination
geometries, whereas BaUbbp and SrUbbp complexes
contain UO7 units with pentagonal bipyramidal coordination
environments. The pH and the monovalent/divalent metal cations have
significant effects on the topology of these structures. These compounds
fluoresce at room temperature owing to emission from the uranyl units.
