Item Synthesis, Characterization and Biological Studies of Mixed Paracetamol - Ascorbic acid Metal Complexes(World Bank Assisted National Agriculture Research Projects (NAARP), Faculty of Science, University of Port-Harcourt, Nigeria, 2016-09-25) Babamale, H. F.; Lawal, A.; Oloyede, E. A.; Rajee, O. A.Mixed ligand-metal complexes of Paracetamol and Ascorbic acid were synthesized using FeCl2.4H2O, CuCl2.2H2O, NiCl2.6H2O, CoCl2.6H2O and ZnSO4 salts based on two concentrations (3mmol and 5mmol). The complexes were characterized using some physical techniques such as melting point, solubility, conductivity measurement and spectroscopic analyses such as UV-Visible spectroscopy, Atomic absorption spectroscopy, and Infrared spectroscopy. Based on the physical and spectroscopic results, the coordination of the metal was through the phenolic oxygen and carbonyl oxygen in paracetamol while it was through the carbonyl oxygen and C-2 hydroxyl group in ascorbic acid. The complexes were also screened for their antimicrobial activities against some isolates of Enterococcus faecalis, Staphylococcus aureus, Clostridium difficile, Klebsiella sp., Helicobacter pylori
