Pentaaquadioxouranium(VI) triflate–18-crown-6

Abstract

The uranyl ion in pentaaquadioxouranium(VI) bis(trifluoromethanesulfonate)-1,4,7,10,13,16-hexaoxacyclooctadecane, [UO 2 (H 2 O) 5 ](CF 3 SO 3 ) 2 .C 12 H 24 O 6 , is equatorially surrounded by five O atoms from water molecules. The CF 3 SO 3 - ions and the crown ether are not part of the uranyl coordination polyhedron but are linked to the U atom via hydrogen bonds
