Abstract: A series of coordination polymers of the general formula  [M(BDC)(Azoles)(H2O)].xH2O, Azoles=2-aminobenzothiazole (ABZ), 2-amino-thiazole (AZ), 2-amino-4-methylthiazole (AMTZ), M = Zn(ІІ) and Cd(ІІ) and H2BDC = 1,4-benzenedicarboxylate and has been prepared and characterized. The complexes are air stable, insoluble in common organic solvents but partially soluble in dimethylformamide (DMF) and dimethylsulphoxide (DMSO). The structure of the complexes has been assigned based on elemental analysis, electronic spectral studies, IR, thermal analysis, X-ray diffraction, Scanning electron microscope and Biological activity. Thermogravimetry (TG), derivative thermogravimetry (DTG) and differential thermal analysis (DTA) have been used to study the thermal decomposition of the complexes. The kinetic parameters have been calculated making use of the Coats-Redfern and Horowitz-Metzger equations.
