Here, the photochemical behavior of [Tc2Cl8]2– was investigated in acetonitrile. The speciation of Tc before and after irradiation at 254 nm was performed by UV-visible spectroscopy and electrospray ionization mass spectrometry (ESI-MS). Upon irradiation at 254 nm, [Tc2Cl8]2– was unstable, the scission of the Tc ≡ Tc unit occurred and the complex [TcCl4(CH3CN)2] was identified. The disappearance rate of [M2Cl8]2– (M = Tc, Re) under irradiation has been measured and was ~7.5 time faster for Tc than for Re.
