The title compound, [SnBr4(H2O)2]·3H2O, forms large colourless crystals in originally sealed samples of tin tetrabromide. It constitutes the first structurally characterized hydrate of SnBr4 and is isostructural with the corresponding hydrate of SnCl4. It is composed of SnIV atoms octahedrally coordinated by four Br atoms and two cis-related water molecules. The octahedra exhibit site symmetry 2. They are arranged into columns along [001] via medium–strong O—H
O hydrogen bonds involving the two lattice water molecules (one situated on a twofold rotation axis) while the chains are interconnected via longer O—HBr hydrogen bonds, forming a three-dimensional network.
