چکیده انگلیسی
[N (CH3)4]2 PdCl4hybrid compound was synthesized and studied by X-ray powder diffraction patterns, differential scanning calorimetry (DSC), and impedance spectroscopy. It is crystallized at room temperature in the tetragonal system with P4/mmm space group and the refined unit cell parameters are aâ¯=â¯bâ¯=â¯8.831â¯Ã
, câ¯=â¯11.415â¯Ã
. Four phase transitions at T1â¯=â¯348â¯K, T2â¯=â¯398â¯K, T3â¯=â¯462â¯K and T4â¯=â¯472â¯K were detected by DSC measurements and confirmed by the variation of fp, Ïg and Ïdc as a function of temperature. The equivalent circuit was attributed based on the Z-View software, and the (AC) electrical conduction in [N(CH3)4]2PdCl4 was determined by two processes based on Elliot's theory: non-overlapping small polaron tunneling model (NSPT) in phase I and IV and the correlated barrier hopping model (CBH) in phase II and III.
