The structure of the title compound, 25-ethyl-2,5,12,15,22,28-hexaoxa-25-azatetracyclo[27.4.0.06,11.016,21]tritriaconta-1(29),6(11),7,9,16(21),17,19,30,32-nonaene, C28H33NO6, does not exhibit a binding cavity for cations, but is collapsed in on itself. The conformation is unique among known tribenzo-21-crown-7 structures, and may be a result of intermolecular (C—H...π) and intramolecular (C—H...O) hydrogen bonding.
