The heat capacity of thallium(I) n-heptanoate has been remeasured on a new sample on which the preparative procedures were modified to eliminate the 1-1 (salt + acid) complex (soap) in a previously studied sample.The sub-ambient heat capacity of a new highly pure thallium(I) n-heptanoate is characterized by one set of transitions between 262 and 272 K and another transition at 301 K.The lowest transition temperature at 262.1 K has a maximum of Cp,m ca. 559 R.Next, a bifurcated pair (at 268.6 and 271.4 K) have Cp,ms ca. 300 R, and the highest transition (at 301.0 K) has a maximum Cp,m ca. 1697 R.The corresponding values of ΔtrsS0m for the two sets are about 2.24 R and 1.10 R.At 298.15 K the values of ΔT0S0m, ΔT0H0m, and Φ0m(T) are 39.79 R, 5979 R * K, and 19.74 R.Smoothed thermodynamic functions at selected temperatures are tabulated through melting.
