The title compound, [SnBr4(C4H8S2)] {systematic name: catena-poly[[tetrabromidotin(IV)]-μ-1,4-dithiane-κ2 S: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.

This work presents experimental data on the surface and grain boundary energies of tin dioxide nanoparticles at room temperature and high temperature conditions (quenched from 1300°C), and a discussion of impacts on the fundamental understanding of the nondensification mechanism of SnO 2 during sintering. The results were obtained using a combination of water adsorption microcalorimetry, high-temperature oxide melt drop solution calorimetry, and scanning electron transmission microscopy. At room temperature, the average surface and grain boundary energies of anhydrous SnO 2 were 1.20 6 0.02 and 0.71 6 0.08 J m À2 , respectively. At high temperature, SnO 2 showed a surface energy of 0.94 6 0.03 J m À2 . This remarkable decrease was attributed to the lower oxygen pressure and was associated with a decrease in contact angle during sintering. This observation indicates a moderate but significant thermodynamic reason behind nondensification behavior of SnO 2 in addition to common kinetic descriptions: high sintering temperatures and atmospheres cause smaller dihedral angles that decrease sintering stresses.
