Technetium(IV) chloride is the chemical compound composed of technetium and chlorine with the formula TcCl4 which has been investigated as a method of separating technetium from other volatile chlorides.[2] Colloidal solutions of technetium(IV) chloride are oxidized to form Tc(VII) ions when exposed to gamma rays.

Technetium trichloride[edit]

Technetium trichloride TcCl3 was reported in 2010. It was prepared from ditechnetium(III) tetraacetate dichloride and HCl(g) at 300 °C as a black solid and consists of triangular Tc3Cl9 units with C3V symmetry, with each Tc atom coordinated to two Tc neighbors and five chloride ligands (Tc-Tc bond length 2.44 angstrom).[4]
