Room-temperature large entropy change in a new hybrid ferroelastic with unconventional bond-switching mechanism

We presented a reversible bond-switching ferroelastic phase transition at near room temperature in a novel organic-inorganic hybrid, (Me3NNH2)2[Co(CN)6Na(H2O)], to afford a latent heat of 43.7 kJ kg‒1 and a large entropy change of 146 J K‒1 kg‒1.
