Some new complexes of Mn(II), Fe(II), Co(II), Ni(II)and Cu(II) metal ions were synthesized of macrocyclic ligand derived from 2,6,diacetyl pyridine and 4-Hydrazino-4-oxobutanoic acid(succinic acid hydrazide) and the chelates were characterized by analysis ,magnetic , electronic and infrared spectral studies. The electronic spectra of the metal complexes indicate trigonal bipyramidal geometry of the complexes.
