Li(2)Sn(OH)(6).
Hydrothermally prepared dilithium tin hexahydroxide crystallizes in the monoclinic system (space group P2(1)/n), with the Sn atom at a site with -1 symmetry and all other atoms in general positions. The Sn coordination polyhedron is made up of six hydroxide groups. The Li atom is tetrahedrally coordinated by oxygen, with the tetrahedra sharing two corners and one edge with the adjacent Sn octahedra. Hydrogen bonds between the OH groups provide additional bonds in the framework.
