Thermal properties of facial and meridional uns-cis-[Co(eddp)gly]. 0.5H(2)O complexes were investigated by means of DSC and TG techniques. It was shown that the processes of thermal decomposition of these complexes are multi-step degradation processes, which can also be well separated into individual steps, depending on the molecular symmetry. Thus, the process of thermal degradation of the meridional isomer of the above complex consists of 4 well-separated steps in the temperature interval from 100 to 500 degrees C. The corresponding kinetic and thermodynamic parameters of this process were determined, and a possible mechanism is discussed.
