dc.description.abstract Polynuclear coordination complexes of the two first row transition elements copper and zinc with the two ligands dimethylglyoxime and paraphenylene diamine, containing nitrogen donor atoms, have been prepared in this paper. This work concerns the synthesis and characterization of the two new synthesized polynuclear complexes (namely CDP and ZDP). The two complexes are derived from Cu(II) and Zn(II) chelates with uni- negative dimethyl glyoximate (DMG) as equatorial ligand and neutral PPD as axial ligand were synthesized in aqueous alcoholic basic media, under reflux conditions. Structural studies based on analytical, FTIR, Electronic, XRD spectral and magnetic data reveal the formation of stable crystalline polynuclear complexes CDP (Cu2+, DMG, PPD) and ZDP (Zn2+, DMG, PPD). In these, the metal ion- DMG (metal dimethylglyoximate) chelates are approximately square planar, in which the planes are connected by PPD ligand. It is proposed that the Cu2+ based complex is penta-nuclear with overall octahedral coordination geometry and the Zn2+ based complex is di-nuclear with a square pyramidal geometry. This was an unfulfilled attempt to synthesize MOFs, which resulted in di-(Zn2+) and penta-(Cu2+) nuclear complexes. en_US
