*2.8. Thermal Analysis*

The thermal stability of compounds **1**, **2** and **3** was evaluated by TGA experiments performed from room temperature to 900 ◦C. All of the complexes showed good thermal stability, and this indicated the strength of their corresponding networks. The least thermally stable compound was the 1D polymer **1**, which lost its coordinated water molecules (exp. 3.02%, calcd. 3.88%) at 110 ◦C. From 190 to 650 ◦C, the consecutive loss of the organic ligand and the anion occurred. Despite their different covalent dimensionality, compounds **2** and **3** were stable up to 180 ◦C and then began to decompose in a process that ended at 650 ◦C, as in compound **1**.
