The thermal decomposition of compound 1 and compound 2 takes place by three separate steps in the range of 30-700°C. The first step is at 120-210°C corresponding to the loss of crystal water molecules. The second and third steps (270-380°C) are contributed to the loss of organic acids and the collapse of the framework.
