Abstract
The Co(II), Ni(II), Cu(II) and Zn(II) complexes with 8-hydroxyquinolin e-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 s uggested on the basis of elemental analysis, IR, H-1 NMR spectroscopy and conductivity measurements. The complexes are all formulated as fou r-coordinate. Some complexes showed enhanced antimicrobial activity re lative to the free ligand.
