Hydrothermally prepared dilithium tin hexahydroxide crystallizes in the mon
oclinic system (space group P2(1)/n), with the Sn atom at a site with (1) o
ver bar symmetry and all other atoms in general positions. The Sn coordinat
ion polyhedron is made up of six hydroxide groups. The Li atom is tetrahedr
ally 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.
