Abstract

New complexes prepared by the reaction of N,N’-bis(3-methoxysalicylidenimino-1,3-diaminopropane) (H2L) with Ni(II), Zn(II) and Cu(II) ions are reported in this paper. The H2L ligand is structurally characterized by elemental analysis, NMR, infrared, UV-Vis spectroscopies, conductance and magnetic room temperature measurement. The mononuclear complex of Ni(II) (C19H24N2NiO6) is characterized by single X-ray diffraction. The compound crystallizes in the orthorhombic system in the space group Pnma with the unit cell parameters a = 7.3754(5) Å, b = 21.9576(13) Å, c = 11.5546(6) Å, α = 90°, β = 90°, γ = 90° The ligand H2L acts in tetradentate fashion in its di-deprotonated form.  Two coordinated water molecules complete the coordination sphere. The environment around the Ni(II) center is best described as an octahedral geometry.

Keywords: Schiff base, X-ray, mononuclear complex, tetra dentate
