Popis: | In this communication, we report the synthesis and characterization of two uranium(VI) complexes with acetone oxime (HL1) and α-benzoin oxime (H2L2). These complexes have been characterized on the basis of elemental analyses, infrared, UV-Visible absorption and 1H NMR spectra. The reaction of acetone oxime, CH3(C˭NOH)CH3, with U(VI) leads to the formation of a monomeric coordination complex of the formula UO2(H2O)2(L1)2 (1), whereas reaction of α-benzoin oxime, C6H5(C˭NOH)(CHOH)C6H5, with U(VI) leads to the formation of a dimeric coordination complex of the formula [U2O4(OH)2(L3)(HL4)]·H2O (2) where L3=(C6H5)C(O−)˭C(N˭O)(C6H5) and HL4=(C6H5)CH(O−)CH(NHOH)(C6H5) are two new deprotonated ligands derived from H2L2. |
