Abstract:
Crystals of the title compound are hexagonal, a=b,13.722(5) β, c=7.504(2) Å, with two molecules per unit cell. Systematic absences ore consistent with space group P63/m. The structure was solved by the heavy-atom method and was refined to a final residual index, R=0.059 for 3139 unique reflections. The molecule consists of a cation (Eu(H20)9)3+ and an anion ((CF3S03)3)3- connected by hydrogen bonds. The metal atom is coplanar with three water oxygen atoms which are called the capping or equatorial oxygens. Another two sets each consisting of three oxygen atoms are lying in a plane symmetrically above and below the equatorial plane. A tricapped trigonal prism of nine water oxygen atoms surrounds the nine coordinated Eu ion.
