The structure was confirmed by elemental analysis, IR, UV-vis, 1H NMR and X-ray single crystal diffractometry and the composition of the compound is identified as C16H26N8O2S2. The preliminary anti-bacterial activity tests showed the Schiff base possesses an inhibition activity towards Escherichia Coli, Staphylococcus aureus and Bacillus subtilis.展开更多

The structures of the ligands and complexes were characterized by elemental analysis, IR, 1H NMR and UV spectroscopy. The bacteriostatic test showed that the ligands were more bioactive than the complexes.展开更多
