TGA and DSC curves of the materials are collected in Figure 6a–c. The TG-DSC curves of the strontium complex precursor show two steps of TG decomposition and two sharp DSC peaks. The first decomposition step of [Sr(C2O4)(H2O)2] at 180–200 °C is related to dehydration of two coordinated water molecules with mass loss, found: 17.55% and Anal. Calcd: 17.01%. A strong exothermic peak at 195 °C is due to the evaporation of water molecules. The second thermal degradation step (450–525 °C) is assigned to elimination of one carbon monoxide with mass loss, found: 13.50%, Anal. Calcd: 13.23%. The strong endothermic peak at 480 °C is ascribed to decomposition of anhydrous strontium oxalate to strontium carbonate and carbon monoxide [30]. The exothermic elevation following endothermic carbonate formation is attributed to the evolution of CO2 after disproportionation of the evolved carbon monoxide to give carbon dioxide and carbon [31]. The residual part (69%) corresponded to formation of strontium carbonate, Anal. Calcd: 69.75%. The TG-DSC results are consistent with the precursor structure of [Sr(C2O4)(H2O)2].
