✦ Synopsis

Recently, considerable interest has been paid to polychelates of polymeric ligand with transition metal ions in order to improve their electrical properties. Some polymeric ligand complexes of Cu(II), Ni(II), and Co(II) have been synthesized, followed by chemical and physical characterization to emphasize their structure and evaluate their electrical behavior. Direct current (dc) and alternating current (ac) electrical conductivities were measured at variable temperatures (300 -50 K). Relative dielectric permittivity ⑀Ј, dielectric loss factor ⑀Љ, and loss tangent tan ␦ were measured and discussed in relation to the presence of transition metal ions.
