Abstract

Abstract The Knudsen mass loss effusion technique was used to measure the vapour pressure of crystalline tris(pentane-2,4-dionato)ruthenium(III) as a function of temperature between 398.18 and 413.15 K using three different effusion holes. From the temperature dependence of the vapour pressure, the standard molar enthalpy of sublimation at the mean temperature of the experimental temperature range, 405.7 K, was derived as 139.7 ± 2.5 kJ mol −. Using an estimated value of Δ cr g C p o = −50 J K −1 mol −1, the standard molar enthalpy of sublimation at 298.15 K was calculated as 145.1 ± 2.5 kJ mol −1.
