Title: Photochemical behavior of the quadruply metal-metal bonded [Tc 2Cl 8] 2– anion in acetonitrile

Here, the photochemical behavior of [Tc 2Cl 8] 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, [Tc 2Cl 8] 2– was unstable, the scission of the Tc ≡ Tc unit occurred and the complex [TcCl 4(CH 3CN) 2] was identified. The disappearance rate of [M 2Cl 8] 2– (M = Tc, Re) under irradiation has been measured and was ~7.5 time faster for Tc than for Re.
