Vibrational spectroscopic force field studies of dimethyl sulfoxide and hexakis(dimethyl sulfoxide)scandium(III) iodide, and crystal and solution structure of the hexakis(dimethyl sulfoxide)scandium(III) ion.
Hexakis(dimethyl sulfoxide)scandium(III) iodide, [Sc(OS(CH(3))(2))(6)]I(3) contains centrosymmetric hexasolvated scandium(III) ions with an Sc-O bond distance of 2.069(3) angstroms. EXAFS spectra yield a mean Sc-O bond distance of 2.09(1) angstroms for solvated scandium(III) ions in dimethyl sulfoxide solution, consistent with six-coordination. Raman and infrared absorption spectra have been re...
متن کاملSulfur K-Edge X-Ray Absorption Spectra for Dimethyl Sulfoxide in the Solvated Thallium(III), Indium(III), Gallium(III) and Aluminum(III) Ions
The sulfur K-edge X-ray absorption near edge spectra (XANES) of the hexakis(dimethyl sulfoxide) solvated trivalent group 13 ions, Al, Ga, In and Tl, in the solid state show larger splitting and different intensity distribution of the main sulfur 1s electronic excitations than for the uncoordinated dimethyl sulfoxide molecule. The transitions have been interpreted by density functional calculati...
متن کاملSynthesis and Crystal Structure of a Novel Six-Coordinate Gallium (III) Complex
The reaction of gallium (III) nitrate octahydrate with the proton transfer compound (pydaH2)2+ (pydc)2– ( where pyda is 2,6-pyridinediamine and pydcH2 is 2,6-pyridinedicarboxylic acid) leads to the formation of (C5H8N3) [Ga(C7H3NO4)2] · 4H2O · CH3OH. The crystal system of the anionic complex is triclinic with space group Pī and two molecules per unit cell. The unit cell parameters are a=10.23...

متن کاملConformational preferences of alanine tripeptide in water, trifluoroethanol and dimethyl sulfoxide studied by vibrational spectroscopy
Alanine tripeptide is a good model molecule to analyze a conformational distribution of an unstructured peptide backbone, to study a competition between the intraand intermolecular hydrogen-bonding, as well as the favourable solvation conditions. In our work, we used three different spectroscopic techniques, the Raman and infrared (IR) spectroscopy, and the vibrational circular dichroism (VCD) ...
