Synthesis, Characterization and Bioactivity Study of Few Metal Complexes of Curcumin with 2-(1H-Benzimidazol-2-yl) Aniline

Abstract

We have synthesized many metal (II) complexes using curcumin L1 as the major ligand and 2-(1H-Benzimidazol-2-yl) aniline L2 as a supporting ligand. The complexes were characterized by spectroscopy methods such as; molar conductivity, elements microanalysis, Fourier-transform spectroscopy (FT-IR), UV-vis, and mass spectroscopy. Both curcumin ligands and L2 were found to be capable of binding to M(II) and metal ions via their two N atoms, according to the data. The formula for the complexes is the same. [M (L1)(L2)H2OCl], where M is Ni(II), Co(II), Cu(II), Cd(II), and Hg(II) (II). Octahedral complexes are proposed for the prepared compounds. The bio-actives suggested that the complexes are effective against bacteria and fungus on a mild to moderate level.

“…The first factor (charge) cannot be the primary cause of this difference because all ions have the same charge. Both the majority of the solution and the adsorbent mass are affected by size during the diffusion process [22][23][24][25][26]. This theory predicts that Co (II), Ni (II), and Cu should have the highest adsorption rates (II), but the rate of decrease in the Co (II) adsorption rate and also the unrestricted linear growth of an adsorbed component indicate that there is still another process taking place in addition to adsorption, and that is the Co (II) oxidation by metal oxide.…”
