Abstract
Spectroscopic properties of UO22+ complexes with diethyl benzylphosphonate (C6H5CH2P(O)(OCH 2CH3)2) (L1) and diethyl (carboxymethyl)phosphonate ((CH3CH2O)2P(O) CH2COOH) (L2) were investigated using absorption and luminescence spectroscopy. Studied compounds were characterized using CHN microanalytical procedures, infrared spectroscopy and by single crystal X-ray diffraction. Uranyl ion forms with the studied ligands complexes of general formulae [UO2(L1)2(NO3)2] and [UO2(L2)2(NO3)2]. In the crystal structures, the uranyl groups are coordinated in the equatorial plane by six oxygen atoms, and the coordination polyhedra of uranium ions are close to hexagonal bipyramid, with uranyl oxygen atoms in apexes. © 2013 Elsevier Ltd.
