文摘

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 2.18Å . The results are discussed with those obtained by Raman spectroscopy and single crystal X-ray diffraction.
