Synthesis and Characterization of 2-Butoxyethylxanthate Complexes with Iron(II), Cobalt(II), Nickel(II), Copper(II) and Zinc(II) and their Adducts with Nitrogen Base Ligands

New complexes and adducts of xanthate of the general formula [M(2-BuoEtxant)2] and [M(2-BuoEtxant)2.nL] Where M= Fe(), Co(), Ni(), Cu() and Zn(), and (2-BuoEtxant)=2-Butoxyethylxanthate, and n=2 when L= pyridine; Isoquinoline, -picoline, 3,5-lutidine, n=1 when L= ethylenediamine, (1,10)-phenanthroline, have been prepared and characterized by metal analyses, infrared, conductance measurements, electronic absorption spectra and susceptibility measurements. Magnetic moment and electronic spectra, indicate that the complexes of type [M(2-BuoEtxant)2] are of tetrahedral geometry while the complexes of type [M(2-BuoEtxant)2.nL] have an octahedral geometry.
