Effect of conformation of cyclic sulfide ligands on the mode of complexation to silver salts

The cyclic trisulfide 1,3,5-trithiane has a flattened chair conformation. It forms with AgSO3CF3 a dimeric complex wherein each silver is tetracoordinated bearing three sulfides and one triflate ion as ligands. On the other hand 1,4-dithiane, which also has a chair conformation, forms an infinite polymer with AgO2CCF3 wherein each silver is coordinated to two different dithianes and two different CF3CO2 ligands.
