N2 - 1H NMR titration of 18-crown-6 with diphenyliodonium triflate and dibenziodolium triflate indicated that the acyclic iodine(iii)-containing species has a higher binding constant value compared with the cyclic analogue. Formation of triple associates diphenyliodonium⋯18-crown-6⋯diphenyliodonium was observed in CD3CN. DFT calculations and QTAIM analysis indicated that the acyclic iodonium salt forms a higher number of interactions with the crown ether compared with the cyclic cation, which results in the formation of triple associates. The formation of dibenziodolium⋯18-crown-6⋯dibenziodolium triple associates turned out to be energetically unfavorable, which agrees with the experimentally obtained data.
