Thermodynamic and electrical properties of aminophenol and anthranilic acid complexes with some transition metals

Thermodynamic and electrical functions of aminophenol and anthranilic acid complexes with Mn(II), Fe(II), Co(II), NO) and Cu(II) were determined. DeltaG(0), DeltaH(0) and DeltaS(0) were calculated with the help of stability constant values at different temperatures. It was found that the complexing processes have an exothermic nature. The studied complexes behave like semiconductors. The conduction takes place according to hopping mechanism. To show the composition of complexes conductometric and photometric titrations, IR spectra, thermal analysis and X-ray diffraction techniques were employed.
