Synthesis, Spectroscopic Identification for Mixed-Ligand Complexes and Evaluating Their Biological Effectiveness

Abstract

in this paper show Mix ligand composed of (HL1) Dimidone and (HL2) 1,2-dibenzothiophene were allowed to react with next metal ions: Cobalt (III), Manganese (II), iron (III), Cobalt (II), Nickle (II), Cupper (II), Zinc (II) and Cadmium (II) individually forming stable metal complexes with different geometries as indicated using various techniques. The formation of the complexes as well as the geometries of the complexes were detected by Fourier-transform-infrared, mass_spectra, elemental analysis and electronic spectra. Moreover, the solubility of the compounds was tested in various solvents including: CHCl3, THF, DMF, DMSO, C2H5OH and H2O. Furthermore, the vital effectiveness was tested toward two types of bacteria gram negative bacteria (Spuedomonas & Escherichia coli was abbreviate (E. Coli) and positive bacteria ( Staphylococcus aureus was abbreviate Staph. Aureas & Bacillus) and two types another of fungi (Aspergillus niger & Fuzaium) giving different inhibition values (either effective or noneffective) as detailed in the manuscript.
