Coordination polymers of glutaraldehyde with glycine metal complexes: synthesis, spectral characterization, and their biological evaluation

Nahid Nishat, Sumaiya Hasnain, Swati Dhyani and Asma    

Abstract: Glycine metal complexes were prepared by the reaction of glycine with Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) in 1 : 2 molar ratio. Thereafter their condensation polymerization was done with glutaraldehyde to obtain polymer metal complexes. All the synthesized polymer metal complexes were characterized by elemental analysis, FT-IR, 1H-NMR, and UV-Vis spectrometry, magnetic susceptibility, and thermogravimetric studies. The analytical data of all the polymers agreed with 1 : 1 molar ratio of metal complex to glutaraldehyde and magnetic moment data suggest that PGG-Mn(II), PGG-Co(II), PGG-Ni(II), and PGG-Cu(II) have an octahedral geometry around the metal atom, whereas the tetrahedral geometry was proposed for PGG-Zn(II) polymer. The PGG-Mn(II) and PGG-Cu(II) showed octahedral geometry. Thermal behavior of the polymer metal complexes was obtained at a heating rate of 10°C min-1 under nitrogen atmosphere from 0°C to 800°C. The antimicrobial activities of synthesized polymers were investigated against Streptococcus aureus, Escherichia coli, Bacillus sphaericus, Salmonella sp. (Bacteria), Fusarium oryzae, Candida albicans, and Aspergillus niger (Yeast).
