Synthesis, Spectroscopic Studies of Some Transition Metal Complexes of Schiff Bases Derived from Diamine Compounds

Abstract

The present work include preparation of three ligands (Schiff base) by condensation of (Phthaldialdehyde) with
1,3-diamino-2-propanol) to give ligands (L)

L: (1Z,6Z)-4,5-dihydro -3H-2,6-benzodiazonin-4-ol

To characterize the structure of prepared ligands and their complexes, elemental analysis (C.H.N),Infrared
Spectroscopy (IR), Nuclear Magnetic Resonance Spectroscopy( 1 H-NMR),Mass Spectra and Molar conductivity
echniques were applied . The results showed that:
- The complexes of [Co(III) and Cr(III)] for ligand have shown octahedral configuration.
- Complexes of [ Ni(II)] with ligands have shown tetrahedral configuration.
