A number of new coordination polymers derived from Co(II), Cu(II) and Zn(II) with BDC=1,4-benzenedicarboxylate, Him = imidazole or Bimz = benzimidazole was prepared and characterized. The structure of the coordination polymers was assigned based on elemental analysis, FT-IR, electronic spectral studies, thermal analysis (TG, DTG and DTA), scanning electron microscope (SEM) and X-ray powder diffraction. The general formula of the complexes are {[M(BDC)(Him)(H2O)].xH2O}n and {[M(BDC)(Bimz)2].6H2O}n where M = Co(II), Cu(II) or Zn(II), x= 5 or 7. During heating in dynamic air atmosphere, the complexes lose all water molecules in one step and the anhydrous compounds decompose stepwise to the corresponding oxides in the final step. The kinetic parameters were calculated making use of the Coats-Redfern and Horowitz-Metzger equations.
