Abstract
The heat capacity for tris-hexafluoroacetylacetonate of aluminium (Al(C5HF6O2)3 or tris(1,1,1,5,5,5-hexafluoro-2,4-pentanedionate) aluminium (III)) within a temperature range (9.83–299.76) K has been measured by the adiabatic method. The functional behaviour of sample’s heat capacity was analysed. No phase transition-related anomalies in the heat capacity behaviour were found. Crystal lattice anisotropy of a studied complex was evaluated. The Debye temperature at 0 K was calculated. The obtained data were used to calculate smoothed values of heat capacity, entropy, enthalpy, and reduced Gibbs energy in a temperature range of 0 K to 300 K. They have the following values at 298.15 K: C°p,m = (608.3 ± 1.0) J K−1 mol−1, Δ0298.15S°m = (786.5 ± 2.1) J K−1 mol−1, Δ0298.15H°m = (106.91 ± 0.20) kJ mol−1, Φ°m = (428.0 ± 1.4) J K−1 mol−1. The value of the absolute entropy were used to calculate the entropy of formation of Al(C5HF6O2)3 (cr) at T = 298.15 K.
