Abstract
The organic–inorganic hybrid compound (C6H9N2)2ZnI4 was prepared by the slow evaporation method at room temperature. The single crystal X-ray diffraction results indicated that the (C6H9N2)2ZnI4 crystal was a monoclinic system with the space group P21/c at room temperature. The compound displayed typical Zero-dimensional (0D) consists of two [C6H9N2]+ cation and one anionic tetrahedral [ZnI4]2−. The sample presented relatively perfect thermal stability up to 260 °C and wide band gap about 3.33 eV which was consistent with the theoretical value. Furthermore, the electrical properties were characterized by impedance spectroscopy with the 209 Hz–5 MHz frequency from 308.15 K to 333.15 K. The alternating current (AC) conductivity of the compound was discussed using Jonscher’s law: σf=σdc+Afs and the conduction could be attributed to the correlated barrier hopping (CBH) model. Therefore, this kind of organic–inorganic hybrid compound will be a promising candidate for optical and electronic applications.
