Octafluorocubane or perfluorocubane is an organofluorine compound with the formula C8F8, consisting of eight carbon atoms joined into a cube, with a fluorine on each corner. It is a colorless sublimable solid. It has been of longstanding theoretical interest, but was not synthesised until 2022, when it was prepared in several steps from a cubane carboxylic ester beginning with its heptafluorination. According to X-ray crystallography, the C-C distances (1.572 Å) in octafluorocubane are identical in length to those in the parent cubane.
