Journal Title:Journal of Chemical, Biological and physical sciences

A novel hexadentate nitrogen donor [N6] macrocyclic ligand, ie. Hexa azabipyH2 (L) has been synthesized. Cr(III) and Cu(II) complexes of this ligand have been prepared and characterized by elemental analyses, molar conductance measurements, magnetic susceptibility measurements, mass, 1H NMR (ligand), IR, electronic and EPR spectral studies. On the basis of molar conductance the Cr(III) complexes may be formulated as Cr(L)X3 and Cu(II) complexes may be formulated as Cu(L)X2, where X= Cl-, Br-, NO3 -, and CH3COO-. On the basis of IR, electronic and EPR spectral studies an octahedral geometry has been designated to Cr(III) and tetragonal for Cu(II) complexes.
