Encapsulated chloride coordinating with two in–in protons of bridgehead amines in an octaprotonated azacryptand

An encapsulated chloride in a thiophene-based cryptand is bridged by two in–in protons of tertiary amines with an N⋯Cl− distance of 3.048(3) Å, similar to that observed in Park and Simmons' katapinand chloride complex.
