| 520 | 3 | |a Redox behavior of UVIO2(dbm)2DMSO (dbm = dibenzoylmethanate, DMSO = dimethyl sulfoxide, 2VI) and structural properties of UVO2+ complexes have been investigated with cyclic voltammetry and IR spectroelectrochemical technique, respectively. As a result, it was confirmed that 2VI is quasi-reversibly reduced to [UVO2(dbm)2DMSO]- (2V) without any successive reactions, and that 2V is stable in DMSO. The formal potential for the redox couple, 2V/2VI, is -1.362V vs . the ferrocene/ferrocenium ion redox couple. The IR spectra measured at various applied potentials show a shift of the peak due to the asymmetric stretching (ν3) of O=U=O from 906 to 775cm-1 with the reduction from 2VI to 2V. From the ν3 peak positions, U=O distances of 2V and 2VI were estimated as 1.82 and 1.76Å by Badger´s rule. | |
