Two Schiff base iodide compounds as iodide ion conductors showing high conductivity

Here, we reported the crystal structures, dielectric and conducting properties of two Schiff base iodide compounds [m-BrBz-1-APy]I(3) (1) and [o-FBz-1-APy]I(3) (2). The Schiff base cations build irregular channel frameworks, and the polyiodide anions are located in the channel. The impedance spectra...

Sumario:Here, we reported the crystal structures, dielectric and conducting properties of two Schiff base iodide compounds [m-BrBz-1-APy]I(3) (1) and [o-FBz-1-APy]I(3) (2). The Schiff base cations build irregular channel frameworks, and the polyiodide anions are located in the channel. The impedance spectra demonstrated that the two compounds show intrinsic iodide ion conductance with higher conductivity of 1.03(4) × 10(−4) S cm(−1) at 343 K for 1 and 4.94(3) × 10(−3) S cm(−1) at 353 K for 2. The dielectric modulus analysis further confirmed that the conductance contributed to the migration of iodide ions.
