The synthesis of ligand [H3N2O6] including the preparation of the compound bis-(2Hydroxybenzamide) propane. Then the reaction of this compound with one mole of paraformaldehyde obtained the ligand. The complexes of the ligand with Ni+2 and Cu+2 ions were prepared by reacted the metal salts with ligand in 1:1 ratio. The prepared compounds were characterised by [IR, UV-Vis, 1H, 13C, 31P NMR spectroscopy] and the physical method. The spectral studies showed the geometry around Ni ion is octahedral, while the geometry around the Cu ion is square planar.
