Characteristic of some other pentafluorides, the compound is volatile but exists as an oligomer in the solid state. ==Preparation and structure== It is prepared by treating tantalum metal with fluorine gas.〔Priest, H. F. "Anhydrous Metal Fluorides" Inorganic Syntheses McGraw-Hill: New York, 1950; Vol. 3, pages 171-183.〕 NbF5 is prepared similarly. Solid and molten TaF5 is tetrameric, consisting of four TaF4 centers linked together via bridging fluoride centers. Gaseous TaF5 adopts the trigonal pyramidal structure with D3h symmetry.〔Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001.
