Composition change of uranium perchlorates with organic ligands upon mechanochemical activation of exchange processes

Results of studies on the effect of mechanochemical activation of ligand exchange processes in uranyl perchlorate-dimethylsulfoxide are presented. Spectroscopic data show that mechanical activation of the exchange process in this system results in the replacement of H₂O in the first coordination sphere of uranyl UO₂²⁺ by DMSO to form nanocrystals with a defined ligand sphere. Possible factors governing the noted features are considered. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 75, No. 2, pp. 213–216, March–April, 2008.
