N2 - An evaluation of the lattice enthalpy of a uranyl salt was made for the first time, yielding for UO2F2 the value ΔHlat298/kJ mole-1 = 2330. This permitted the estimation of numerous other important enthalpy values, such as the heats of formation ΔHf298(UO22+(g))/kJ mole-1 = 1210, and ΔHf298(UO2(NO3)2(TBP)2(l))/kJ mole-1 = -4425, the lattice energy ΔHlat298(UO2(NO3)2(c))/kJ mole-1 = 1936, the hydration energy ΔH0(UO22+)/kJ mole-1 = -1361, and the bond energy between the uranyl cation and the phosphoryl oxygen of a TBP molecule in the isolated adduct molecule of 200 kJ mole-1. The entropy change for the formation of the adduct has also been evaluated.
