Some novel complexes of Cu(II) and Zn(II) with nitrogen and sulphur containing macrocycles: Synthesis and characterisation
Author(s): Dr. Sanjay Kumar, Priyanka and Rabindra Singh
Abstract: A novel series of complexes of Cu(II) and Zn(II) with macrocyclic ligands 1,5,8,12-tetraaza-6,7,13,14-dibenzo-2,4,9,11-tetramethyl cyclotetradeca-1,4,8,11-tetraene(L1) and 1,7,9,15-tetraaza-4,12-dithia-2,6,10,14-tetraoxocyclohexadecane (L2) have been synthesised by template condensation method and characterised on the basis of elemental analyses, molar mass determination, molar conductance and magnetic susceptibility measurements, IR and UV-Vis spectroscopic investigations. The complexes were found to have molecular formula as [M(L1)(H2O)2]Cl2 and [M(L2)(H2O)2]Cl2, where M=Cu(II) and Zn(II). Complexes of Cu(II) were paramagnetic while those of Zn(II) were diamagnetic as expected for a d10 system. Magnetic moment values and the range of uv spectral bands suggested octahedral geometry for the complexes. The nature of metal-ligand bonds was established by IR spectral investigations. All the complexes were found to have 1:2 electrolytic nature.
