Thermochemical studies of crystalline tris (acetylacetonato) manganese (III) [Mn(C5H7O2)3(c)] compound through calorimetry


M Pathak, Raghvendu Pathak

The present work gives an account of the thermochemical studies of crystalline tris (acetylacetonato) manganese (III) compound. The heat of combustion (ΔcH) and thereby standard heat of formation (ΔfH°) of crystalline tris (acetylacetonato) manganese (III) [Mn(C5H7O2)3(c)] has been measured experimentally with the help of static oxygen bomb calorimeter at 298 K and the values so obtained for ΔcH and the ΔfH° have been compared with those available in literature to judge the efficacy of the present process. The values for ΔcH and ΔfH° in the solid phase have been experimentally found to be - 8047∙371 k J mol-1 and - 1341∙46 ± 15 kJ mol-1 respectively.
