- W2347701473 abstract "Dehydroabietylamine 5-nitro-sacyldiene Schiff base(L) and its Cu2+, Zn2+, Co2+ and Ni2+ complexes were synthesized and characterized by IR, 1H NMR, UV-vis spectrometric spectra, molar conductivity and single crystal X-ray diffraction. Cu(L)2 forms a classical complex with N2O2 donor, it is in monoclinic system with space group C2 and cell dimensions: a=3.699 6 nm, b=1.083 5 nm, c=1.285 6 nm, α=90 °, β=103.36 °,γ=90 °. The effects of organic solvents of various polarities on the UV-vis spectrometric spectra of ligand and complexes were investigated. With change of solvent,the ligand can change from enol to keto structure. The metal complexes are easily dissolved in organic solvents.The molar conductivities indicate their non-electrolyte properties in all these organic solvents such as DMF, chloroform and toluene. UV-vis spectrometric spectra change with the polarity of solvent, both ligand and complex show solvatochromism in these solvents. The ligand and its metal complex were also screened against S.aureus, B.subtilis and E.coli, the antibacterial screening data showed that both ligand and complex exhibit biological activity, while Cu complex was the strongest one. The obtained results indicated that polarity of solvent has great effect on the UV-vis spectrometric spectra of ligand and complex, the biological activity of metal complex has intimate relationship with metal." @default.
