Abstract :
Measurements of X-ray diffraction (XD) on 1 and 3 M Sc(CIO4)3 aqueous solutions and of X-ray absorption fine structure (XAFS) on a 4.6 M Sc(CF3SO3)3 aqueous solution have been made at room temperature. Both the XD and XAFS data have revealed that about seven water molecules are bound to a Sc3+ ion with a Sc3+−H2O distance of 2.18 Å. The results are discussed with those obtained by Raman spectroscopy and single crystal X-ray diffraction.
