dc.description.abstractFour complexes CoScplx, CoNcplx, NiScplx and NiNcplx were synthesized from 2-hydroxynaphthalene -1carbaldehyde using 2-thiosylaniline and 2-aminoaniline as Co-Schiff bases. The physical and analytical data of the ligands and complexes such as Molecular weight, colour, melting point and percentage yield as well as molar conductivity and elemental composition were determined. The compounds were characterized using FTIR, UV-VIS and MS Analyzers. FT-IR results revealed loss of –OH bond noticed in the ligands at complexation due to deprotonation and utilization of phenolic OH in bond formation. The UV-VIS spectral data recorded more peaks with Schiff bases and complexes with 2-aminoaniline as a result of more chromophoric groups. The MS result determined m/z of the molecular ions and their fragments confirming the structure of synthesized compounds. The complexes demonstrated more antifungal and antibacterial activities more than the ligands hence can be incorporated into antibiotics drugs in future.
