A large room-temperature entropy change in a new hybrid ferroelastic with an unconventional bond-switching mechanism

abstract

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