摘要：

Ten new mononuclear complexes having general formulae [ML2](ClO4)(2), M = Cu(II), Co(II), Ni(II), Mn(II) and Zn(II), [ML2](SO4), M = Co(II), Ni(II) and [ML2(H2O)(2)](SO4), M = Cu(II), Mn(II) and Zn(II), L = 2-acetyl-pyridyl-isonicotinoylhydrazone have been synthesized and characterized based on elemental analyses, IR spectroscopy, UV-Vis-NIR, EPR, as well as thermal analysis and determination of molar conductivity and magnetic moments. The structures of [CoL2](ClO4)(2) are accomplished by single crystal X-ray diffraction. The coordination sphere is formed by two N, N, O tridentates 2-acetyl-pyridyl-isonicotinoylhydrazone ligands, or by two N, O bidentate 2-acetyl-pyridyl-isonicotinoylhydrazone and two water molecules. Biological activity studies reveal a moderate activity of complexes against gram-negative and gram-positive bacteria.
