Abstract
The Co(II), Ni(II), Cu(II) and Zn(II) complexes with 8-hydroxyquinoline-5-sulfonylhydrazone are described. It has been found that the ligand can coordinate to metal ion as a monobasic bidentate chelating agent and it can form di- and trinuclear complexes while acting as a dibasic tetradentate one. The structure of the isolated complexes have been suggested on the basis of elemental analysis, IR, 1H NMR spectroscopy and conductivity measurements. The complexes are all formulated as four-coordinate. Some complexes showed enhanced antimicrobial activity relative to the free ligand.
