Synthesis, Spectral Characterization, Thermal and In vitro Antimicrobial Studies for Novel Co(II) and Ni(II) Complexes of (N,N'-(1,2-Phenylene)Bis(2-Aminobenzamide)
Keywords:Synthesis, Spectral, Thermal Studies, Metal Complexes, Antibacterial, Antifungal Activity
Novel metal complexes of Co(II) and Ni(II) have been prepared from reaction of their different salts with previously prepared ligand (L) namely (N,N'-(1,2-phenylene)bis(2-aminobenzamide). Synthesis ligand and its metal (II) complexes (1-5) were reported and characterized with the help of analytical and physiochemical analysis as elemental, IR spectra, thermal (TG/DTG), UV-Vis, magnetic susceptibility and molar conductance in DMF, On the view of the previous data and measurements, the structure and composition species behave as mononuclear and octahedral geometry has been proposed for all the complexes except for complex (1) adopted tetrahedral structure. Furthermore, the in vitro antibacterial Staphylococcus aureus (ATCC 25923) as Gram-positive strain, Escherichia coli (ATCC 25922) as Gram-negative strain and antifungal Candida albicans (ATCC 10231) have been studied for all samples using disc diffusion method against Ampicillin and Fluconazole as positive controls, respectively. The results show that complexation facilitates the activity of most studied metal complexes than the free ligand.
