Abstract: The title compound, [Tc(CO)₆]ClO₄, was synthesized by the reaction of [TcCl(CO)₅] with AgClO₄, followed by acidification with HClO₄ under a CO atmosphere. The [Tc(CO)₆]⁺ cation has close to idealized octahedral geometry, with the bond angles between cis-CO groups close to 90° and the Tc-C bond lengths in the range 2.025 (3)-2.029 (3)Å. The perchlorate anion is disordered over two crystallographically equivalent half-occupied positions. The Tc atom in the [Tc(CO)₆]⁺ cation is located on an inversion centre.
