Dielectric Behaviour of Metal Complexes Cu (II), Ni (II) and UO2 ((VI) Of the Ligand Oxaloanilic Acid Hydrazone

Abstract

Abstract: The dielectric behaviour and molecular structure of metal complexes Cu(II),Ni(II) and UO2((VI) of the ligand oxaloanilic acid hydrazine have been investigated using Time Domain Reflectometry (TDR) technique in the frequency range 10 MHz to 10GHz. Cole-Davidson model has been applied for fitting the complex permittivity spectra [ ε* (ω)]. The parameters εs –the static permittivity, τ- the dielectric relaxation time are evaluated at different temperatures from 2880K to 3330K and are discussed in respect of their molecular structural behaviours. The thermodynamic parameters, such as ΔH* - molar enthalpy, ΔS* - the molar entropy are obtained using Eyring.s rate equation. In the light of such data the possible structures of the present complexes are discussed.
