Synthesis and Characterization of Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) Complexes with Hexa azamacrocyclic Ligands Derived from Thiosemicarbazide

Abstract: Some transition metal (II) complex are synthesized with thiosemicarbazide Ligands L1= dicyclohexen [1,6,7,9,14,15] hexaaza [2,5,10,3] tetra one [8,13] dithiacyclohexadecane and L2= dicyclohexyl [1,6,7,9,14,15] hexaaza [2,5, 10, 13] tetraone [8,13] dithiaCyclohexadecane. These complexes are characterized by elemental analysis, molar conductance magnetic susceptibility measurements, IR, electronic spectral studies. The molar conductance measurements of the complexes in DMSO correspond to non-electrolytic nature and the complexes may have octahedral geometry.
