Preparation and Characterization and Biological Activities of Mixed Ligand Complexes of Co+2, Ni+2 and Cu+2 with 3- amino-2- methyl -2-phenyl-2H-benzol [e][1,3]thiazin-(3H)- one and Glycine


A new ligand was synthesized and characterized by (FTIR) spectroscopy, Uv-vis and C.H.N. A speciation of mixed ligand complexes of Co(II), Ni(II) and Cu(II) with 3- amino-2- methyl -2-phenyl-2H-benzol [e][1,3] thiazin-(3H)- one and Glycine were prepare , isolated and characterized by (FTIR), Uv-vis spectra, atomic absorption , conductivity and magnetic susceptibility measurements. The biological activity for the prepared complexes was studied against selected kind of bacteria and fungus, for bacteria, gram negative as E coli and gram positive as staphylococcus aureus. The molecular structures of prepared complexes suggested according to the result of IR spectra, Uv-vis , magnetic susceptibility and molar conductance ,were octahedral for Co(II) and Ni(II) while square planner geometry for the Cu(II) complex .
