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. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Mizuoka Koichiro aut Ikeda Yasuhisa aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/9-11/2004(2004-11-01), 631-635 0033-8230 92:9-11/2004<631 2004 92 ract https://doi.org/10.1524/ract.92.9.631.54979 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.92.9.631.54979 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Mizuoka Koichiro aut NATIONALLICENCE 700 1- Ikeda Yasuhisa aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 92/9-11/2004(2004-11-01), 631-635 0033-8230 92:9-11/2004<631 2004 92 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
