TG/DTG/DTA curves of coordination polymer are displayed in Figure 6, Figure 7, Figure 8 and Figure 9 and their thermal decomposition data are tabulated in Table 3 and Table 4. Thermal decomposition of all the coordination polymers was carried out at a heating rate of 10 °C min−1 under nitrogen atmosphere over the temperature range 28–1220 °C. The structural transformation is observed by TG curves which is supported by DTG and DTA studies. Thermal analysis has proved to be useful in determining the crystal water content in the coordination polymers and their thermal stability as well as decomposition mode under controlled heating rate. The matter released at each step of degradation was identified through attributing the mass loss at given step to the similar mass calculated from molecular formula of investigated polymer, comparing that with literature values for relevant coordination polymers considering their temperature. The thermal stability properties were evaluated by TG/DTG/DTA methods whose results revealed good thermal stability for all the synthesized coordination polymers. Moreover, the limited oxygen index values were calculated on the basis of char yield obtained at 1200 °C and revealed good thermal stability of the coordination polymers.
