Complexes of uranyl β-diketonates with sulphoxides
TLDR
The proton magnetic resonance spectra of the synergistic complexes of uranyl β-diketonates with dihexyl sulphoxide as the neutral donor give a multiplet consisting of eight lines for the terminal methylene group protons adjacent to the sulphur atom of the sulphoxide as discussed by the authors.Abstract:
The proton magnetic resonance spectra of the synergistic complexes of uranyl β-diketonates with dihexyl sulphoxide as the neutral donor give a multiplet consisting of eight lines for the terminal methylene group protons adjacent to the sulphur atom of the sulphoxide and a triplet for the β-methylene protons. This conforms to an ABX2 pattern arising as a result of nonequivalence of the two protons of the terminal methylene group as a result of steric hindrance to free rotation about the C-S bond. The presence of such restricted rotation has been adduced as evidence for a direct donor-metal bond.read more
