Synthesis and characterization of hetero cyclic imine and its metal complexes for anticorrosion application

Abstract

The novel hetero cyclic imine and its Ni(II), Zn(II), Cd(II) metal complexes derivatives have synthesized and its thermal behavior is investigated using TGA/DTG technique, spectral studies by Fourier-transform infrared spectroscopy, 1H NMR, UV–Visible, Electron-spin resonance (ESR), Mass, magnetic properties by magnetic susceptibility data, conductivity by molar conductance and evaluated for anticorrosion application. The results found show that the loss of weight was measured up to 800◦C and stability of the complexes with its cyclic imine ligand depended on the order Zn(II) > Ni(II) > Cd(II) of central metal cation. The spectral data describes the general formula C32H30N2O8X(H2O)2(where X = Ni(II), Zn(II) and Cd(II) of the octahedral complexes. The anti-corrosion and its controlling characteristics of the above synthesized organic compounds proved based on the properties of molecules, mainly the p-electrons of the imine group and p-electrons of aromatic substituents. The presence of azomethine group in the complexes exhibited the good anti-corrosion properties.
