Standard enthalpy of the formation of Ba[AuF6]2(cr.)

The enthalpies of the interaction of Ba[AuF₆]₂(cr.) with water and an aqueous potassium hydroxide solution have been measured in a calorimeter with an isothermal shell at 298.15 K. The standard enthalpy of the formation of the studied compound Δ_f H° Ba[AuF₆]₂(cr.) = −2341 ± 10 kJ/mol has been found by two independent methods based on these results and literature data.
