A series of coordination polymers of the general formula {[M(ndc)(azoles)(H2O)].XH2O}n (where M =Co(II), Cu(II) and Zn(II), ndc = 1,4-naphthalenedicarboxylate, azoles = 2-aminothiazole and 2- aminobenzothiazole, x=0, 1 or 2) has been prepared and characterized. The coordination polymers have been characterized based on elemental analysis, FT-IR and electronic spectral studies magnetic measurements and thermal analysis. Thermogravimetry, derivative thermogravimetry, and differential thermal analysis were used to study the thermal decomposition of the complexes. Non isothermal kinetic parameters were calculated making use of the Coats-Redfern and Horowitz-Metzger equations. Catalytic performances of the two of the complexes for the degradation of methyl orange by sodium persulfate have been investigated.
