Availability of fixed urea groups is confirmed by infrared spectroscopy. According to elemental analysis, the content of functional groups at the obtained non-porous xerogels is 1.2-1.6 mmol ? g-1. The complexation between urea group of some alkoxysilanes and ions of rare earth elements was studied. Using infrared spectroscopy shows the formation of complexes of composition 1:3 for Me: ligand.
