Synthesis and Characterization of Some transition metal complexes with mannich bases Derived from 8- Hydroxyqinoline

Abstract

New bidentate mannich base having nitrogen and oxygen atom was
prepared by condensation of the formaldehyde with piperidine and 8-
hydroxyquinoline in ethanol. An ethanolic solution of the prepared ligand
was reacted with an ethanolic solution of metal ions Cr(III ), Fe(III), Co(II)
, Ni(II) and Cu(II) to give new complexes. All the prepared compounds
were isolated and characterized by their melting points, FTIR and UV-Vis.,
spectroscopy. Elemental analyses have been performed using C, H , N and
atomic absorption technique , and the magnetic susceptibility have also
been measured.
