Tantalum - Wikipedia

Tantalum halides span the oxidation states of +5, +4, and +3. Tantalum pentafluoride (TaF 5) is a white solid with a melting point of 97.0 °C. The anion [TaF 7] 2-is used for its separation from niobium. The chloride TaCl 5, which exists as a dimer, is the main reagent in synthesis of new Ta compounds. It hydrolyzes readily to an oxychloride.
