Preparation, Structural Study, Theoretical Treatment and Biological Activity of Cr (III), Ni (II), Cd (II) and V (IV) Complexes of Tetradentate Ligand Bis [4-Phenyl-3 (2- Propenyl) Thio-1, 2, 4-Triazole-5yl] Methane

Some transition metal complexes Cr (III), Ni (II), Cd (II) and V (IV) Complexes of olefinic bistriazole as a ligand have been synthesized and characterized. The prepared complexes were identified and their structural geometries were suggested by using Flame Atomic Absorption technique, FT-IR and Uv-Visible Spectrophotometer as well as to Magnetic Susceptibility and Conductivity measurement. Semi-empirical methods (PM3 and MINDO/3) were carried out to evaluate the vibration frequencies, heat of formation (ΔHºƒ) and binding energy (ΔEb) for all metal complexes. And it is also studying their biological activity against two selected microorganisms (pseudomonas aeruginosa and staphylococcus aureus).
