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 thethermochemical 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.
