Octafluorocubane or perfluorocubane is an … 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. Octafluorocubane has attracted interest from theorists because of its unusual electronic structure, which is indicated by its susceptibility to undergo reduction to a detectable anion C8F−8, with the free electron trapped in the inside of the cube.lectron trapped in the inside of the cube.
, 八氟立方烷是一种有机化合物，化学式为C8F8，它是立方烷分子上的氢原子全部被氟取代的产物。它是挥发性固体，在2022年被合成出来之前只有理论研究。它可由立方烷羧酸酯为原料经氟化得到。X射线衍射表明分子中的C-C键键长（1.572 Å）和母体立方烷的一致。 它特殊的电子结构有着理论研究，如它容易被还原为阴离子C8F8−而被检测出来，其电子位于立方结构的内部。
