Infrared spectra and structure of tetravalent uranium chloride nanoclusters in electron-donor solvents

We have studied the IR absorption spectra of tetravalent uranium chlorides in electron-donor solvents. We discuss the changes in these spectra on coordination of the solvent molecules to the tetravalent uranium. We consider the participation of water molecules in this process. On this basis, we draw the conclusion that clusters form with coordination number equal mainly to six.
