Na 2 SO 4 BF 3 , synthesized in a closed vessel from BF 3 and Na 2 SO 4 at 603 K, crystallizes in the triclinic space group P $\bar{1}$ ( a = 6.6033(2), b = 6.6328(2), c = 6.6349 (1) Å, α = 84.542(2), β = 84.458(1) and γ = 65.762(1)°). The novel fluorooxo anion [SO 4 BF 3 ] 2– displays a structure similar to the disulfate anion S 2 O 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.
