Table 2.

Comparison between the hydrogen binding enthalpies at 298 K (∆H298, bind, in kJ/mol) for the systems in Fig. 4 obtained in the solid state and in bulk aqueous solution

∆H298,bind (kJ/mol)
Model Solid state Aqueous solution
4A N/A* N/A
4B –14.8 –6.8
4C –13.4 –5.3
4D –66.7 –42.7
4E –52.9 –32.9

*N/A corresponds to the absence of hydrogen binding enthalpy.
