AbstractX-Ray structural investigations of the 1:1 crystalline complexes formed between [Diquat][PF6]2 and (i) the bisformyl dibenzo-30-crown-10 derivative 2 and (ii) the dimethyl dibenzo-30-crown-10 derivative 4 reveal that in both cases, charge transfer, as well as electrostatic binding and weak [C-···O] hydrogen bonding combine to give the cortlexes their remarkable stabilities; in acetone solution, the stability constants for the 1:1 complexes involving 2, 3, and 4 are 2100, 50000, and 48000 M-1, respectively. © 1985.
