It is built-up of SnCl4(H2O)2 octa-hedral units (point group symmetry 2) and lattice water mol-ecules. An intricate three-dimensional network of O-H⋯O and O-H⋯Cl hydrogen bonds between the complex molecules and the lattice water molecules is formed in the crystal structure.

Mentions: The tin(IV) ion in tin(IV) chloride octa­hydrate is situated on a twofold rotation axis and is coordinated by four Cl atoms and two water mol­ecules in a cis-octahedral geometry (Fig. 1 ▶), as was observed before for the tetra- and penta­hydrate (Shihada et al., 2004 ▶). In addition, three water mol­ecules (O1, O2 and O3) are located around the octa­hedra as non-coordinating water mol­ecules. Every water mol­ecule of the first coordination sphere is connected with two water mol­ecules of the second shell by hydrogen bonds. The chlorine atoms form only one hydrogen bond towards ‘free’ water mol­ecules of the second shell (Fig. 2 ▶).
