Synthesis, crystal structure, and kinetics of the thermal decomposition of the nickel(II) complex of the Schiff base 2-[(4-methylphenylimino)methyl]-6- methoxyphenol

Abstract

A new dinuclear complex, [Ni2(H2O)L 4]·5H2O, consisting of chelating bidentate and bridging tridentate coordinated 2-[(4-methylphenylimino)methyl]-6-methoxyphenol (HL) Schiff base ligands and water molecules has been synthesized using a traditional method. The structure of this complex was characterized by FTIR and UV/Vis spectroscopy and thermogravimetric analyses (TG-DTG) and further confirmed by singlecrystal X-ray diffraction. Its crystal structure is of monoclinic system, space group P21/c with a = 13.2837(5) Å, b = 27.3886(10) Å, c = 17.5415(6) Å, α = 90°, β = 108.429(2)°, γ = 90°, V = 6054.7(4)Å3, Z = 4. The crystal structure reveals that there is a Ni·Ni core, with a separation of 3.183 Å. Its thermal decomposition kinetics were also studied. © 2009 by the authors; licensee Molecular Diversity Preservation International, Basel, Switzerland.
