*2.6.1.1. Two-dimensional network of water molecules in the three phases interpretation*

In order to understand how water molecules are found in the material and thus to make one website speedily of the kinetic parameters during the process of dehydration, two-dimensional networks of water molecules are presented in three different phases (see Figure 9). Note that the water molecules are organized along two-dimensional planes alternating the position between coordinated octahedral (defined by the position of the metal) sites and the position in the existing cavities between polyhedral.

**Figure 9.** Two-dimensional representation of the network of water molecules in the different lamellar systems for (a) L1 phase, (b) K phase, and (c) L0 phase. Each red sphere is a water molecule without the hydrogen atoms.
