An unexpected TTFAQ donor-fluorene acceptor reaction resulting in a novel salt: 2,6-dihexyloxy-9,10-bis(4,5-dimethyl-1,3-dithiol-2-ylium)-anthracene bis(2,5,7-trinitro-4-bromo-9-cyanofluorenide) dioxane trisolvate

Reaction of the electron acceptor 2,5,7-trinitro-4-bromo-9-dicyanomethylenefluorene (1) and the electron donor 2,6-dihexyloxy-9,10-bis(4,5-dimethyl-1,3-dithiol-2-ylidene)-9,10- dihydroanthracene (2) in dioxane resulted in the formation of a novel type of salt with the previously unknown 2,5,7-trinitro-4-bromo-9-cyanofluorenide anion (3(-)): (2)(2+).(3)(2).3C(4)H(8)O(2).
