Аннотация

The structure and spectroscopic properties of two mixed-ligand uranyl complexes, [(CH3)4N]2· [(UO2)2(NO3)4(OH)2] and [(UO2)2(NO3)4(H2O)2]·2Im (Im = imidazole), were studied by single crystal X-ray diffraction and by vibrational and photoluminescence spectroscopy. The previously made assumption that the latter compound contains electrically neutral complexes [(UO2)2(NO3)4(H2O)2] was found to be erroneous; actually both compounds contain dimeric anions [(UO2)2(NO3)4(OH)2]2–.
