CF 3 -substituted sulfonium cations as efficient chalcogen bond donors towards cyanometalates

S–(CF 3 )Thianthrenium and S–(CF 3 )dibenzothiophenium cations form potent chalcogen bonds (ChBs) with [Mo(CO) 5 CN] − , yielding S 2 N 2 supramolecular motifs. Crystal structures reveal shorter S⋯N contacts opposite the CF 3 group compared to the aryl substituents. The energetic features of the ChB...

Description
Summary:S–(CF 3 )Thianthrenium and S–(CF 3 )dibenzothiophenium cations form potent chalcogen bonds (ChBs) with [Mo(CO) 5 CN] − , yielding S 2 N 2 supramolecular motifs. Crystal structures reveal shorter S⋯N contacts opposite the CF 3 group compared to the aryl substituents. The energetic features of the ChBs have been studied using DFT calculations demonstrating the structure guiding role of ChBs.
