The low-temperature heat capacity of PuH1.9, where the major plutonium isotope was 242Pu, has been determined from 8 to 350 K.The results of this investigation at 298.15 K have been adjusted to correspond to stoichiometric plutonium dihydride: PuH2.Standard molar thermodynamic quantities were obtained for PuH2 at T = 298.15 K: C0p,m(T) = (43.50 +/- 0.44) J*K-1*mol-1; S0m(T) = (72.84 +/- 0.73) J*K-1*mol-1; 0m(T) - H0m(0)> = (85.93 +/- 86) J*mol-1; and -0m(T) - H0m(0)>/T = (44.02 +/- 0.44) J*K-1*mol-1.These have been combined with experimental high-temperature heat capacities (340 to 600 K) of a sample of PuH2.0, where the major plutonium isotope as 239Pu, to give the thermodynamic functions of PuH2 over the temperature range from 298.15 to 600 K.
