In (1,4,7,10,13,16-hexaoxa-2,3: 11,12-dibenzocyclooctadeca-2,11-diene)potassium triiodide, [K(C20H24O6)]I3, the K+ ion is coordinated to the six ether O donors of the macrocycle [K-O 2.716 (4)-2.779 (4) Å] and to atom I3 at a distance of 3.6002 (13) Å; I1-I2 is 2.8741 (7) and I2-I3 2.9838 (7) Å. Pairs of symmetry-related [K(dibenzo-18-crown-6)]I3 molecules aggregate, with an unusually short distance of 3.184 (3) Å between the K+ ion and the centroid of one of the benzo groups.
