Filling the equatorial garland of uranyl ion: its content and limitations

Abstract : Crystal structure determinations on the uranyl ion complexes [H2N(CH3)2]2[UO2(bpdc)2], (1), (bpdc = 2,2'-bipyridine-3,3'-dicarboxylate), [pyH]2[UO2(btfac)(NO3)2](NO3), (2), (btfac = 1-phenyl-4,4,4-trifluorobutane-1,3- dionate), [H2dabco][UO2(nta)]23H2O, (3), (dabco = 1,4-diazabicyclo[2.2.2]octane; nta = nitrilotriacetate) and [Ni(cyclam)UO2(edta)].2H2O, (4), (cyclam = 1,4,8,11- tetrazacyclotetradecane; edta = ethylenediaminetetraacetate) have provided further examples of U(VI) in tetragonal-, pentagonal and hexagonal-bipyramidal coordination environments. Consideration of each structure within the context of those of known relatives has been used to assess the influence of factors in addition to repulsions within the primary coordination sphere on the equatorial coordination number of U(VI)
