摘要：

S-(CF3)Thianthrenium and S-(CF3)dibenzothiophenium cations form potent chalcogen bonds (ChBs) with [Mo(CO)(5)CN](-), yielding S2N2 supramolecular motifs. Crystal structures reveal shorter S & ctdot;N contacts opposite the CF3 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.
