TRANSPORT PROPERTIES OF SOME NEW THIADIAZOLE SCHIFF-BASE COMPLEXES

The samples under investigation were prepared by the conversional method where pure
analar chemical (BDH) where used. FTIR were performed to assure the preparation of the
samples in the proper form. The real and imaginary parts of the dielectric constant were
measured for the different samples at different temperature as a function of the applied
frequency. The obtained data were interpreted in view of the polarization mechanism and the
ionic radii of the different metals used. The increase in the transition point with frequency
means that the frequency acts as a pumping force pushing the change carriers from one
conduction state to another. The addition of more than one element of different ionic radii
affect directly on the physical properties because at certain radius some of these ions do not
enter the structure.
