Abstract:  A common and a cation-exchange techniques of preparation of tri-n-butylphosphate (TBP) uranyl perrhenato and TBP-uranyl pertechnetato complexes, UO₂(XO₄)₂ . 2TBP (X = Re, Tc) are described. The i.r. spectra of these complexes were investigated and discussed from the viewpoint of formation of coordination bond between the ligand (ReO₄^-, TcO₄^- ) and the central atom. In the TBP-complexes both the perrhenate and pertechnetate anions exhibit bidentate coordination on the uranyl ion.
