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

Abstract: 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^-)₂·3C₄H₈O₂.
