CRYSTAL-STRUCTURE OF SCANDIUM(III) TRIFLATE ENNEAHYDRATED

The crystal structure of scandium(III) trifluoromethanesulfonate ennea hydrated has been determined by single crystal X-ray diffractions. Cry stal data space group P6(3) m, a = 12.979(1) Angstrom, c = 7.755(2) An gstrom. The structure has been refined to R = 0.079 (R(w) = 0.074) wit h 449 independent reflections and 61 variables. The structur consists of enneacoordinated complexes [Sc(H2O)(9)](3+), linked through hydroge n bonds by trifluoromethanesulfonate anions. Each anion bridges three complexes forming a couple of hydrogen bonds with each complex. The [S c(H2O)(9)](3+) species is tricapped trigonal prismatic.
