Studies on Novel Co-ordination Polymers Based on 2,5-bis(4-chloro phenylcarbamoyl)terephthalic acid and Divalent Transition Metal Ions

Novel bis-ligand namely, 2,5-bis(4-chlorophenylcarbamoyl)terephthalic acid (BCPCTPA) was synthesized by condensation of anhydride of 1,2,4,5-benzene tetracarboxylic (pyromellitic dianhydride –abbreviated PMDA) with 4-chloro aniline. Co-ordination polymers of this bisligand were prepared with Cu(II), Ni(II), Co(II), Mn(II) and Zn(II) metal salts. All these coordination polymers and the parent ligand were characterized by elemental analysis, infrared spectra, number-average molecular weights, magnetic susceptibilities and by thermogravimetry. The antimicrobicidal activity of all the samples has also been monitored against plant pathogens
