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 complexes were characterized by elemental analysis, XRD, UV, IR and 1H NMR. The crystal structure of the complexes belongs to triclinic system with the cell parameters: a =1 297 1 nm, b =1 621 0 nm, c =2 047 0 nm, α =85 40°, β =88 80°, γ =99 00° for [CuC 30 H 26 N 2O 4·0 5H 2O]; a =1 300 2 nm, b =1 882 6 nm, c =2 127 4 nm, α =86 47°, β =89 23°, γ =99 11° for [NiC 30 H 26 N 2O 4]; a =1 286 5 nm, b =1 596 1 nm, c =2 056 9 nm, α =87 95°, β =93 17°, γ =98 21° for [CoC 30 H 26 N 2O 4], respectively. The N and O atoms in the complexes appeared coordinated directly to the metal ions. A quadridentate chelate may be formed.展开更多
