摘要：
The standard enthalpy of formation of crystalline Mg(BUO5)(2) center dot 4H(2)O at 298.15 K (-5563 +/- 10 kJ/mol) was determined by reaction calorimetry. The heat capacity of the compound was studied over the temperature range 8-340 K by adiabatic vacuum calorimetry, and its thermodynamic functions were calculated. The standard entropy and Gibbs function of formation at 298.15 K (-1692.2 +/- 3.4 J/(mol K) and -5059 +/- 11 kJ/mol, respectively) were determined.
