Solid-state effects of monofluorophenyl substitution in dithiadiazolyl radicals: Impact on S···S and S···N interactions and their classification via Hirshfeld surfaces and fingerprint plots

► We report the first crystal structures of monofluorophenyl dithiadiazoyl radicals. ► Infinite intermolecular S···S contact motifs were observed in both structures. ► Hirshfeld surfaces was used to identify the more subtle intermolecular contacts. ► The molecular topology was assessed using fingerprint and barcode plots.
