As part of the study of the U(VI), Np(VI) and Pu(VI) coordination behavior in the presence of different ligands, were synthesized their mixed ligand complexes with perrhenate- and pertechnetate ions, and organic molecules. Their crystal structure was determined by X-ray diffractometry. Experimental IR spectra of the compounds correlate with their crystal structure. However, a reliable assignment of vibration frequencies in the range 940-900 cm-1 is difficult. In this region, are observed the modes corresponding to AnO22+ and XO4- groups, which can hardly be discriminated
