摘要

Na _2SO _4BF _3, synthesized in a closed vessel from BF _3 and Na _2SO _4 at 603 K, crystallizes in the triclinic space group P1? (a = 6.6033(2), b = 6.6328(2), c = 6.6349 (1) ?, α = 84.542(2), β = 84.458(1) and γ = 65.762(1)°). The novel fluorooxo anion [SO _4BF _3] ~(2-) displays a structure similar to the disulfate anion S _2O _7 ~(2-). Heating the title compound in the absence of BF _3 in the gas phase leads to decomposition even at 553 K, which is below the temperature of synthesis under BF _3 pressure.
