Abstract
A new hydroxo stannate(IV), Sr2Sn(OH)8, has been synthesized by the hydrothermal method. Single-crystal X-ray diffraction shows that this compound crystallizes in the monoclinic space group P21/c with a = 6.006(1) Å, b = 11.058(2) Å, c = 6.129(2) Å, β = 112.98(2)°, V = 374.8(2) Å3, Z = 2, R = 0.022 (I > 2 σ(I)). The structure [Sr(OH)(6/3)(OH)(2/2)]2[Sn(OH)(6/3)] consists of Sn(OH)6 octahedra and Sr(OH)8 triangulated dodecahedra. These Sr(OH)8 and Sn(OH)6 polyhedra form a novel complex 3D packing arrangement that contains channels running along [001], filled with the in-pointing hydrogens of the hydroxo groups.
