title: Diaqua-tetra-bromidotin(IV) trihydrate.
abstract: The title compound, [SnBr(4)(H(2)O)(2)]·3H(2)O, forms large colourless crystals in originally sealed samples of tin tetra-bromide. It constitutes the first structurally characterized hydrate of SnBr(4) and is isostructural with the corresponding -hydrate of SnCl(4). It is composed of Sn(IV) atoms octa-hedrally coordinated by four Br atoms and two cis-related water mol-ecules. The octa-hedra exhibit site symmetry 2. They are arranged into columns along [001] via medium-strong O-H⋯O hydrogen bonds involving the two lattice water mol-ecules (one situated on a twofold rotation axis) while the chains are inter-connected via longer O-H⋯Br hydrogen bonds, forming a three-dimensional network.
