*3.4. Thermal Analysis*

DSC experiments were performed to evaluate the stability of the new phases, as well as to determine the melting points of the new multicomponent phases. Figure 13 shows the DSC of the three **(lidhcl)** and **(lid)** phases.

**Figure 13.** DSC diagrams for **(lid)** phases (**left**) and for **(lidhcl)** phases (**right**).

In the case of the **(lidhcl)** phases, a decrease in the melting point can clearly be seen in the order **(hq)** > **(res)** > **(pyr)**, with apparently no relation with structure effects.

There was a certain tendency with the measured solubilities, which also decreased in the same order, relating the melting point with the apparent solubility.
