Sign in to savethumb|right|200px|The structure of the technetate(VII) ion The pertechnetate ion () is an oxyanion with the chemical formula . It is often used as a convenient water-soluble source of isotopes of the radioactive element technetium (Tc). In particular it is used to carry the 99mTc isotope (half-life 6 hours) which is commonly used in nuclear medicine in several nuclear scanning procedures.

Pertechnetate is poorly hydrated as [TcO4(H2O)n]− and [TcO4(H2O)n-m]−[H3O]+m (n = 1–50, m = 1–4) clusters that have been demonstrated by simulation with DFT. First hydration shell of TcO4− is asymmetric and contains no more than 7 water molecules. Only three of the four oxygen atoms of TcO4− form hydrogen bonds with water molecules.
