In the crystal structures of [3 6 ](1,2,3,4,5,6)cyclophane 1 and the 1:TCNQ (1:1) complex, the cyclophane moiety is observed as the D 6h structure because of the disorder of the molecules with C 6h symmetry. In contrast, the C 6h structure is observed in the crystals of the 1:TCNQ-F 4 (1:1) complex,
