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.
