A series of chelate polymer compounds having formulae {[MnL(H2O)2]n(1)}, {[CoL(H2O)2]2H2O}n(2), {[NiL(H2O)2]2H2O}n(3) and {[CuL(H2O)2]H2O}n(4) were synthesized based on chelating ligand i.e. terphthaoyl-bis (paramethoxyphenylcarbamide) (L). The authenticity of four divalent transition metal chelate polymers were characterized by elemental analysis, infrared, diffuse reflectance spectroscopy, magnetic measurements, X-ray diffraction, thermal and SEM techniques. The infrared spectroscopy supports interaction through nitrogen and oxygen atom of ligand with metal ion. Diffuse reflectance spectral studies suggest an octahedral geometry for Mn (II), Co (II), Ni (II) and Cu (II) chelate polymers, which was further supported by other instrumental technique in present work. Furthermore, solid state electrical conductivity of all chelate polymers have been measured in compressed pellet form over 311 K by two probe method. The morphology behaviour of all polymer compounds was identified by SEM and XRD techniques. The crystalline and amorphous nature of chelate polymer compounds were determined by X-RD technique, while SEM images reveals that, the particle sizes of chelate polymers were found to be between 100-985nm.
