Novel bis ligand namely 2,2’-(4,4’-(biphenyl-4,4’-diylbis(diazene-2,1-diyl))bis(4,1-phenylene)) bis (azanediyl) bis (oxo methylene)dibenzoic acid (BPBA) has been prepared and characterized. The co-ordination polymers based on this bis ligand with transition metal ions like Cu+2,Co+2,Ni+2,Mn+2and Zn+2 were prepared and studied for their metal: ligand (M/L) ratio, IR and reflectance spectroscopies, magnetic properties, number-average molecular weight and by thermogravimetry. All the novel synthesized compounds were screened for their antibacterial and antifungal activities
