In the present study a series of metal complex of [bis (2-amino-5-aryl-1,3,4-thiadiazole]2Cl
(S1-S9) was synthesized by using ultrasound irradiation technique. The metal complex was synthesized
by the reaction between ligand and appropriate metal salts (CuCl2. 2H2O, CoCl2. 6H2O, ZnCl2, MgCl2.
4H2O, NiCl2. 6H2O). The products were obtained in high yield and the reaction time was found to be
shorter. The synthesized metal complexes were characterized by using UV-visible spectroscopy, FTIR,
1H NMR and Mass spectroscopy. The synthesized compounds were investigated for antibacterial potential
against gram positive bacteria (Bacillus subtilis, Staphylococcus aureus) and gram negative bacteria
(Pseudomonas aeruginosa, Escherichia coli). Significant activity was observed for synthesized
metal complexes S6 and S7 against B. subtilis and S. aureus.
