The electrical, structural and thermal properties of copper(II) 4-aminobenzoate and copper(II)

3,5-dinitrobenzoate are reported. The direct current conductivities were analyzed at low (10 < T(K) < 300) and at high temperatures (300 < T(K) < 440). The Mott’s variable range hopping and Arrhenius laws were used as models for the conductivity profiles obtained. The results show that the electronic conduction characteristics of these materials depend on the structure and thermal stability. X-ray powder diffraction, infrared spectroscopy, thermogravimetric analysis and differential scanning calorimetry support the above findings.
