Co-ordination polymers of novel bis ligand namely 5,5'-(6-(4- bromo phenoxy)-1,3,5-triazine-2,4- diyl)bis(azanediyl)bis(2-hydroxybenzoic acid)(CSL-3) have been prepared with various metal complexes viz Zn+2, Cu+2, Ni+2, Co+2 and Mn+2. The novel bis bidentate ligand (CSL-3) is synthesized by condensation of 5-amino salicylic acid with 2,4-dichloro-6- (4-bromo phenoxy)-1,3,5-triazine in presence of base catalyst. All these co-ordination polymers and parent ligand are characterized by elemental analysis, IR spectra and diffuse reflectance spectral studies for their structure determination. The thermal stability was evaluated by thermogravimetric analyses(TGA). In addition, all of the coordination polymers have been characterized by their magnetic susceptibilities. The microbicidal activities of all the samples have been monitored against plant pathogens.
