The solid state structures of seven substituted fluoranthenes were determined by single-crystal X-ray diffraction. All compounds bear electron withdrawing substituents in various positions, giving rise to an excellent opportunity to compare the solid state packing influences of the trifluoromethyl substituent and other electron withdrawing groups (pentafluorophenyl and nitrile groups). It was found that, depending on the substituent and the position of the substituent, the most commonly observed molecular packing motifs in crystals, such as herringbone packing with or without π-π overlap, 1D π-stacking and lamellar 2D π-stacking can be realized. The solid state packing motifs of seven substituted fluoranthenes bearing electron withdrawing substituents in various positions are compared.
