New Methods for the Preparation Nanosized Metal Coordination
Polymers

Research Abstract
Transition-metal coordination polymers [M(ndc) (bpy)(H2O)m]xH2O (where M = Co(II), Ni(II), Cu(II) and Zn(II), ndc = 1,4-naphthalenedicarboxylate, bpy = 4,40-bipyridine; m = 0 or 1; x = 1 or 2) were prepared by reacting the ligands and metal ions at room temperature with the aid of microwave irradiation and sonication methods. The structure of the coordination polymers was assigned based on elemental analysis, FT-IR and electronic spectral studies, thermal analysis, scanning electron microscope and X-ray powder diffraction. Thermogravimetric analysis was also used to follow up the possible thermal decomposition steps and to calculate the thermodynamic parameters of the nano-sized metal complexes. The kinetic parameters were calculated making use of the Coats–Redfern and Horowitz–Metzger equations. All obtained results of the different technics used in our study stated the ability to synthesis the metal coordination polymers of our interest using both microwave irradiation and sonication methods.

Coordination Polymers of Co(II), Cu(II) and Zn(II) Derived from 1,4- Naphthalenedicarboxylate and Certain Thiazoles, Characterization and Catalytic Activity

Research Abstract
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.
