Novel unidentate co-ordination of a crown ether and of a polyethylene glycol to uranium(VI)

Abstract

The syntheses and structural characterizations of [UO2Cl2(OH2)2(1,4,7,10- tetraoxacyclododecane)]·1,4,7,10-tetraxacyclododecane and UO2Cl2(OH2)2(3,6,9,12,15- pentaoxaheptadecane-1,17-diol) have revealed that individual 12-crown-4 and hexaethylene glycol (EO6) molecules can behave as both unidentate donors and hydrogen bond acceptors.
