摘要

Colourless crystals of Li-2[Sn(OH)(6)]. 2H(2)O were synthesized by reaction of SnCl4 with LiOH in aqueous solution. The crystal structure was determined from single crystal data. Li-2[Sn(OH)(6)]. 2H(2)O: monoclinic, P2(1) (Nr.14), a=502.3(1), b=692.3(1), c=1020.2(3)pm, beta=99.78(1)degrees, V=349.6(2).10(6) pm(3), Z = 2, R/Rw = 0.0192/0.0472, N(I) > 2 sigma(I) = 1527, N(Par.)= 54. Within the crystal structure only slightly distorted octahedrally [Sn(OH)(6)](2-) ions are bonded via hydrogen bonds with water molecules forming layers, which themselve are linked by tetrahedrally coordinated Li ions; the structure is in accordance with the IR-data and the results of the Sn-119 solid state NMR-spectroscopy; the hydrat water is eliminated at 117.1 degrees C, the condensation reaction - forming the ternary oxide - takes place at 257.7 degrees C.
