The room temperature ESR spectra of Cu(II) complex yield <g >values, characteristics of square planar geometry. The solid state electrical conductivities of the complexes increase as the temperature increases from 311-383 K, with a band gap of 0.11- 0.21 eV, indicating their semiconducting behaviour. � 2024 World Researchers Associations.
