Crystal structure of tin(IV) chloride octahydrate

The title compound, [SnCl4(H2O)2]·6H2O, was crystallized according to the solid–liquid phase diagram at lower temperatures. It is built-up of SnCl4(H2O)2 octahedral units (point group symmetry 2) and lattice water molecules. 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.
