Synthesis And Characterization of Sulfur Donor Ligand (xanthate) Complexe with Manganese (ll), Iron (ll), Cobalt (ll), Nikel (ll), Copper (ll), And Zinc (ll) And Thier Adduct with Nitrogen Base Ligande

New complexes and adducts of xanthate of the general formula [M(cyclopentyl xant.)2] and [M(cyclopentyl xant.)2.nL] Where M= Mn(ΙΙ) Fe(ΙΙ), Co(ΙΙ), Ni(ΙΙ), Cu(ΙΙ) and Zn(ΙΙ), and (cyclopentyl xant.)2=[Cyclopentyl xanthate ligand], n=2 L= Pyridine, 3-acetyl pyridine & Quinoline n=1, L= ethylenediamine, (1,10)-phenanthroline, the prepared complexes has been evaluated based on their magnetic, electrical, and physical characteristics. And spectral methods 1H-NMR of (cyclopentyl xant.) ligand, Based on the effective magnetic moment and electronic spectra, the structures of the kind [M(cyclopentyl xant.)2] indicate a tetrahedral geometry whereas structures of the kind [M(cyclopentyl xant.)2.nL] has an octahedral geometry. The density functional theory (DFT) calculations of ligands and their complexes were performed by the DFT/B3LYP/6-311++G(d,p) method to obtain the optimized molecular geometry, the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO), and electronic properties , thermodynamic parameters are done for four coordinates
