Low-Temperature Thermodynamic Properties of Cobalt Trisdipivaloyl Methanate

The heat capacity of cobalt trisdipivaloyl methanate Co(C₁₁H₁₉O₂)₃ was measured by the adiabatic method within the temperature range 8.18–301.61 K. The analysis of the functional dependence of the heat capacity did not revealed any thermal anomalies in its behavior. The thermodynamic functions (entropy, enthalpy, and reduced Gibbs energy) were calculated from the measured experimental data on the heat capacity within a temperature range of 0–300 K. The absolute entropy was used to calculate the formation entropy of Co(C₁₁H₁₉O₂)₃ at Т = 298.15 K.
