C6F5XeCl and [(C6F5Xe)2Cl][AsF6]: The First Isolated and Unambiguously Characterized Xenon(II) Chlorine Compounds

: Xenon(II) chlorine compounds can be obtained as the isolable organo derivatives C(6)F(5)XeCl and [(C(6)F(5)Xe)(2)Cl][AsF(6)] (whose cation is depicted) in 85 and 91 % yield, respectively. These compounds decompose vigorously at 36 degrees C and 100 degrees C, respectively, leading to the formation of C(6)F(5)Cl and Xe gas and of C(6)F(5)Cl, C(6)F(6), and [C(6)F(5)Xe][AsF(6)], respectively.
