Abstract
The sublimation parameters of bis(acetylacetoneiminato)nickel(II) NiAim(2) and bis(acetylacetonato)(2,2'-dipyridyl)cobalt(II) CoA(2)dipy in a dynamic vacuum were determined using differential scanning calorimetry (DSC). No ch emical transformations or other physicochemical processes that would change the structure and complicate sublimation of these compounds were observed in the temperature range studied. The calculated enthalpies of sublimation are 106.0 +/- 1.7 kJ/mol for the nickel complex and 244.3 +/- 7.5 kJ/mol fo r the cobalt complex.
