Sumario: | The structure of the title compound, [Sn(2)Br(1.97)Cl(4.03)(OH)(2)(H(2)O)(2)]·2C(3)H(6)O, contains two hexacoordinated Sn atoms bridged symmetrically by two hydroxide groups, with an inversion center in the middle of the planar Sn(2)O(2) ring, half of the molecule being generated by inversion symmetry. The other sites of the distorted octahedral coordination geometry are occupied by halide atoms and water molecules. The structure exhibits substitutional disorder of the halide atoms bonded to the Sn atom, with 0.672 (4) occupancy for Cl and 0.328 (4) for Br for each halide position. The compound crystallizes with two acetone molecules, which are involved in intra- and intermolecular O—H⋯O contacts. The water molecules coordinated to the Sn atoms are also involved in O—H⋯O and O—H⋯X contacts, leading to a polymeric array along the a axis. |
