Synthesis and Characterization of a New Triazene Complexes for Cu(II), Ni(II), Co(II), Zn(II) and Fe(II)

A new series of complexes containing Triazene compound was prepared, Triazene compound was prepared by the diazotization of o-toluidine then reacting with piperidine to give the corresponding triazene compound (1-(o-tolyldiazenyl)piperidine). The complexes M[(2-CH3-C6H3-N=N)-N-C5H10)] 2X2- of Cu(II), Ni(II), Co(II), Zn(II) and Fe(II) with triazene compound (1-(o-tolyldiazenyl)piperidine) has been synthesized by the reacting between copper bromide, hydrate nickel chloride, hydrate cobalt chloride, zinc chloride, and iron bromide in 1:2 mole ratio. It has been isolated in the solid state and characterized by (C.H.N) data, IR and 1H NMR spectroscopy. Six coordinate and octahedral complexes were producted and the results are reported and discussed below.
