Abstract

SYNTHESIS, SPECTROSCOPIC CHARACTERIZATION OF Mn(II), Co(II), Cu(II) AND Ni(II) COMPLEXES WITH MACROCYCLIC LIGAND (L)

Sumedha Gupta, Usha Bansal* and Bhupendra Kumar Sarma

ABSTRACT

Mn(II), Co(II), Cu(II) and Ni(II) complexes of new tetradentate nitrogen donor[N4] macrocyclic ligand(L) i.e. 3,10-dibromo-1,5,8,12-tetraaza-6,7:13,14-dibenzocyclotetradeca-1,4,8,11-tetraene were synthesized and characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, various spectroscopic techniques such as electronic, IR, Mass, 1H NMR, EPR and UV-Vis spectral Studies. The molar conductance values indicated that all the metal complexes were non-electrolytic in nature, in dimethylformamide (DMSO). Metal complexes possessed general composition [M(L)(X)2] where M = Mn(II), Cu(II),Co(II), Ni(II) and L = Ligand and X=Cl-, NO3- and ½SO42-. On the basis of IR Spectral study, it was concluded that ligand contains nitrogen donor [N4] atoms and these donor atoms coordinate with metal ions to form metal complexes. Co(II), Mn(II) and Ni(II), complexes possess octahedral geometry, whereas Cu(II) complexes show tetragonal geometry and [Cu(L)SO4] possess five coordinated trigonal bipyramidal geometry.

Keywords: Magnetic Moment, IR, 1H NMR, Mass, Electronic, EPR spectral Studies.
