Abstract:
The thermal behaviour of an H-bonded molecular network A based on [FeII (CN)6 ]4- anions and organic bisamidium cations 12+ was investigated. Heating was found to induce the partial oxidation of [FeII (CN)6 ]4- into [FeIII (CN)6 ]3- , together with a thermochromic effect and also a loss of crystallinity was evidenced from mid and far FT-IR spectroscopic data, XRPD and DSC/TGA analysis. Rehydration also partially reversed the redox reaction and its colour, and after that, a mixture of A with an amorphous phases was observed. FT-IR spectroscopy revealed that the oxidation of Fe(II) was accompanied by a deprotonation of the cation.

01:15Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
