An X-ray crystallographic investigation of the complex between the diquat dication and dibenzo-30-crown-10, [Diquat.DB30C10] [PF6]2, reveals gross structural features for host-guest complexes (I) and (II) in which weak [C-H ⋯ O] hydrogen bonding and charge transfer are the major components of host-guest binding; these same components are also responsible for the formation of stable and ordered 1:1 solution complexes between dibenzo-3n-crown-n (n = 9-12) and diquat bis(hexafluorophosphate) (2).
