NEW INSIGHTS INTO THE FORMATION OF EXTENDED SUPRAMOLECULAR ARCHITECTURES FROM SIMPLE BUILDING-BLOCKS

Reaction of uranyl acetate with HCl and 15-crown-5 in toluene results in the formation of a liquid clathrate phase from which crystals of (H 5O2)[UO2Cl3(H2O)(2)].(15-crown-5)(2) 1 are deposited; on standing, los s of HCl results in the isolation of a second product [UO2Cl2(H2O)(3)] (16).(15-crown-5)(16) 2 which displays an extremely complex hydrogen b onded chain structure in the solid state.
