Complex of rhodium(III) with acetylacetone (Rh(acac)3) was synthesized, purified and identified for thermochemical study. Vapor pressures of the compound were measured by static and transpiration methods in the temperature range from 398 to 521 K. Thermodynamic characteristics of sublimation process DsubH459.6 and DsubS 459.6 were determined from the experimental data. Heat capacity in the temperature range from 188 to 465 K was measured by using DSC for the first time. Using experimental results, DsubH298.15 and DsubS 298.15 of the compound were derived.
