| Abstract: | Syntheses and Crystal Structures of Y(HSO4)3-I and Y(HSO4)3 · H2O Lath shaped crystals of Y(HSO4)-I are obtained by treatment of Y2O3 with conc. sulfuric acid at 200 °C. Y(HSO4)3-I crystallizes orthorhombic (Pbca, Z = 8, a = 1201.5(1), b = 953.76(8), c = 1650.4(1) pm, Rall = 0.0388). In the crystal structure Y3+ is coordinated by eight monodentate HSO4– groups. Colorless, plate like single crystals of Y(HSO4)3 · H2O grew from a solution of Y2O3 in 85% sulfuric acid upon cooling. In the crystal structure of the triclinic compound (P1, Z = 2, a = 679.8(1), b = 802.8(2), c = 965.9(2) pm, α = 79.99(2)°, β = 77.32(2)°, γ = 77.50(2)°, Rall = 0.0264) Y3+ is surrounded by seven HSO4– groups and one molecule of water. |
