Abstract:

14membered macrocyclic complexes of Cr(III), Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) containing tetraoxo octa aza cyclo hexadecane ligand (L = C6H12N8O4) have been isolated by the template condensation of oxalo dihydrazide and formaldehyde in the presence of corresponding metal chloride and characterized by elemental analysis, UVVisible spectroscopic studies, magnetic moments and conductance measurements. The complexes of the type [M(C6H12N8O4)Cl2] [Where M = Mn, Co, Ni and Cu] and [M(C6H12N8O4)Cl2]Cl [M=Cr and Fe] are all octahedral in nature.
