Abstract
Manganese(II) and cobalt(II) complexes were synthesized with [N4] tetradentate macrocyclic ligand
using different metal salts i.e. MnCl2, Mn(NO3)2, CoCl2 and Co(NCS)2. The ligand was prepared by
condensation of glyoxal and carbahydrazide. All these were characterized by elemental analysis, molar
conductance measurements, magnetic moment, IR, mass, electronic and EPR spectral studies. Elemental
analysis indicates that the complexes have composition MLX2 where (X = Cl–, NO3
–,NCS–). All the
complexes were found to be non-electrolytic in nature so can be formulated as [MLX2]. Infrared
spectra of metal complexes suggest that the ligand behaves as tetradentate. On the basis of magnetic
moment, electronic and EPR spectral data, all the metal complexes were found to be high spin with
octahedral geometry.
