Abstract: The high-temperature thermodynamic properties of dimeric europium dipivaloylmethanate (or tris(2,2,6,6-tetramethyl-3,5-heptanedionato) europium, chemical formula [Eu(C11H19O2)3]2) were studied. A thermogravimetric study was performed to determine the stability of the solid phase. Heat capacity was measured by DSC in the range of (283–487) K. No anomalies in the heat capacity associated with phase transitions were found up to the melting point. Isobaric thermodynamic functions of entropy, enthalpy increment and reduced Gibbs energy were calculated. Accuracy of the obtained results was estimated and the results were compared with the known data.
