Abstract |
2-(Benzothiazol-2-yl)-N'-(2,5-dihydroxybenzylidene)acetohydrazide 에대한새로운일련의 Mn(II), Ni(II), Co(II), Cu(II) 및 Zn(II) 착물을 합성하여 그 특성을원소분석, IR, UV-vis, 1H-NMR, 질량분석, ESR, 자기수자율 및 몰 전기전도도측정에 의하여조사하였다. 이들 착물의기하구조가사각평면 또는 팔면체임을 분광학적 데이터 및 자기적 측정으로부터알았다. 이 리간드와 해당착물의세균에(Aspergillus nigar 및 Fusarium oxysporium) 대한생물학적활성을조사하였다. 그 결과, 금속착물 들은리간드 및 금속이온 모두에비해 더 큰 활성을나타내었다.
New series of Mn(II), Ni(II), Co(II), Cu(II) and Zn(II) of the 2-(benzothiazol-2-yl)-N'-(2,5-dihydroxybenzylidene) acetohydrazide have been synthesized and characterized by elemental analysis, IR, UV-vis, 1H-NMR, mass and ESR spectra, magnetic susceptibility and molar conductivity measurements. The spectral data and magnetic measurements of the complexes indicate that, the geometries are either square planar or octahedral. The biological activity of the ligand and its complexes against fungi (Aspergillus nigar and Fusarium oxysporium) were investigated. The metal complexes exhibited higher activity than both the parent ligand and the corresponding metal ion.
