|Abstract:||16-Membered macrocyclic complexes of Cr(III), Mn(II), Fe(III), Co(II), Ni(II) and Cu(II) containing tetraoxooctaazacyclohexadecane ligand (L=C8H16N8O4) have been isolated by the template condensation of malonodihydrazide and formaldehyde in the presence of corresponding metal chloride and characterized by elemental analyses, infrared, 1H NMR, UV-visible spectroscopic studies, magnetic moments and conductance measurements. The complexes of the type [M(L)Cl2] [where M=Mn, Co, Ni and Cu] and [M(L)Cl2]Cl [M=Cr and Fe] are all octahedral in nature.|
