Abstract

We have synthesized a Schiff base, 2-((E)-((furan-2-yl)methylimino)methyl)benzofuran-3-ol and assessed it using elemental analyses, infrared spectroscopy, nuclear magnetic resonance, mass spectra and thermal analysis (TGA). The complexes' analytical results confirm the synthesis of a 1:2 [M:L] ratio of the formula [ML2], where M corresponds to the ions Cu(II), Ni(II), Zn(II), Mn(II) and L for the deprotonated Schiff base. Metal ions are bidentately coupled to Schiff base via azomethine-N and phenolic-oxygen groups, according to infrared spectra. The disc diffusion technique was used to test the ligand and their metal chelates for their antibacterial properties against the specified microorganisms.
