From the data obtained, it is clear that Cu (II) ishighly active among the coordination polymer of the respective metal.CONCLUSIONThe results at present work show the following conclusions. The design synthesis of new bis-ligand has beenperformed successfully, and analysed by normaly spectral study. A series of some novel coordinationpolymer from bis-ligands with transition metals have been prepared and characterized for their spectral andmagnetic properties. All the synthesized coordination polymer compounds were screened for theirantimicrobial activity. The coordination polymers exhibited behave toxic for gram-negative bacteria (E.coli,samonella typhi and klebsiella promioe) and gram-positive bacteria (Bacillus subtilis and staphylococcusaureus), and plant pathogenic organisms (fungi) used were Aspergillus niger, Candida albicans,Trichoderma harsianum, Mucor mucedo, and Botrytis cinerea microorganisms. In comparison with theligand, coordination polymers were more active against one or more bacterial strains, thus introducing anovel class of metal-based bactericidal agents. The information regarding geometry of the coordinationpolymer was obtained from their electronic and magnetic moment values. The magnetic moment values ofcoordination polymer indicate an octahedral geometry.114 J. Chem. Bio. Phy. Sci. Sec. A, 2012-2013, Vol.3, No.1, 109-116.
