Abstract
In triaquadioxobis luoromethanesulfonato)uranium(VI)-benzo-15-crown-5 (1/2), [UO2(CF3SO3)(2)(H2O)(3)].-2C(14)H(20)O(5), the uranyl ion is in a pentagonal pseudo-planar equatorial environment, consisting of two O atoms from two trifluoromethanesulfonate (triflate) ions and three f rom water molecules. The coordination of CF3SO3- is particularly notab le owing to the poor coordinating character of this ion. Two molecules of benzo-15-crown-5 are hydrogen bonded to the water molecules (one w ater molecule bridging) without any direct interaction with the uranyl moiety.
