【 摘 要 】

The title compound, [SnBr4(C4H8S2)] {systematic name: catena-poly[[tetrabromidotin(IV)]-μ-1,4-dithiane-κ2S:S′]}, represents the first 1,4-di­thiane complex with tin as coordination centre. The asymmetric unit consist of half a formula unit with the tin(IV) atom at the centre of symmetry at 0,0,1/2 (Wyckoff symbol b) and a centrosymmetric 1,4-di­thiane mol­ecule with the centre of symmetry in 1/2,0,1 (Wyckoff symbol c). The tin(IV) atom is coordinated in a distorted octa­hedral manner by the four bromine atoms and two sulfur atoms of two 1,4-di­thiane mol­ecules in a trans-position. Sn—Br [mean value: 2.561 (5) Å] and Sn—S distances [2.6546 (6) Å] are in the typical range for octa­hedrally coordinated tin(IV) atoms and the di­thiane mol­ecule adopts a chair conformation. The one-dimensional polymeric chains propagate along the [101] direction with weak inter­molecular Br⋯Br [3.5724 (4) Å] between parallel chains and weak Br⋯H inter­actions [2.944–2.993 Å] within the chains.
