Characterization and Electrical Properties of [C₆H₉N₂]₂CuCl₄ Compound

Abstract

We report measurements of X-ray powder diffraction, vibrational study, the differential scanning calorimetry (DSC), and the electric properties of a made-up [C 6 H 9 N 2 ] 2 CuCl 4 sample. The alternative current (ac) conductivity of the compound [C 6 H 9 N 2 ] 2 CuCl 4 has been measured in the temperature range 356-398 K and the frequency range 209 Hz-5 MHz. The ColeCole (the imaginer part (Z ) versus real part (Z ) of impedance complex) plots are well fitted to an equivalent circuit model which consists of a parallel combination of a bulk resistance (R) and constant phase elements (CPE). The single semicircle indicates only one primary mechanism for the electrical conduction within [C 6 H 9 N 2 ] 2 CuCl 4 . The variation of the value of these elements with temperatures confirmed the result detected by DSC and dielectric measurements. Thus the conduction in the material is probably due to a hopping or a small polaron tunneling process.

“…6 ). The impedance of the constant phase element ( Z CPE ) is determined from the formula: 31 where Q indicates the value of the pseudo-capacitance of the CPE element and the exponent n determines the phase angle β = n π/2 between the radius of the semicircle and the Z ′ axis in the Nyquist representation. It is assumed that CPE depicts an ideal resistor for n equal to 0 while for n = 1 represent an ideal capacitance.…”

Experimental characterization, machine learning analysis and computational modelling of the high effective inhibition of copper corrosion by 5‐(4‐pyridyl)‐1,3,4‐oxadiazole‐2‐thiol in saline environment

“…However, these spectra show changes in the intensities of two bands, namely an increase in the peak at 275 cm -1 and a decrease in that at 613 cm -1 , as well as slight shifts in these to 279 and 605 cm -1 , respectively. These changes could be associated with the appearance of corrosion on the copper surface and the formation of Cu-Cl (chloride related species) [68].…”
