Synthesis and Characterization of Some Complexes of Manganese(II), Iron(II) and Cobalt(II) With Decylxanthate and Their Adducts With Nitrogen Base Ligands

This research includes the synthesis and characterization of twelve new complexes of mono nuclear xanthate for a number of transition metal ions Mn(II) , Fe(II) , Co(II) and through the interaction with ligand (decyl xanthate potassium) and complexes of formula [M(DEXANT)2] were formed , as : M= Mn(II) , Fe(II) , Co(II) and then the interaction of these complexes with Lewis bivalve bases , to give complexes with the formula [M(DEXANT)2 . L], where : L= 1,10-phenanthroline , 8-hydroxyquinoline, 2,2-Pipyridine. The prepared complexes were characterized by melting point , atomic absorption, micro elemental analysis , infrared , nuclear magnetic resonance spectrum of the proton , molar electrical conductivity , electronic absorption spectra and susceptibility measurements. Magnetic moment and electronic spectra indicated that the complexes of type [M(DEXANT)2] had a tetrahedral geometry, while complexes of type [M(DEXANT)2.L] had an octahedral geometry,The conductivity measurements proved the non-electrolytic behavior of all compounds .
