Structure, dielectric and electric properties of diisobutylammonium hydrogen sulfate crystal

A new organic-inorganic hybrid material, [(CH3)2CHCH2]2NH2(HSO4), was successfully synthesized by the slow evaporation technique. The temperature-dependent X-ray powder diffraction and differential scanning calorimetry measurements revealed the occurrence of two fully reversible phase transitions. Three phases were structurally described by single-crystal X-ray diffraction. This material showed fast proton transport with activation energy of 0.23 eV in the high-temperature phase I.192
