Synergistic extraction of cobalt(II) complexes with toluene-3,4-dithiol in presence of some benzylamines

Research Abstract
The synergistic extraction of cobalt(II) complexes with toluene-3,4-dithiol (TDT) in presence of monobenzylamine (BA), dibenzylamine (DBA) and tribenzylamine (TBA) has been investigated. The stoichiometry of the adducts formed was established from the extraction data. Values of the formation constant,B ex, in presence of the amine ligands have been determined. It is found that the extraction ability decreases in the orderDBA TBA>BA.

Some transition metal chelates of 8-hydroxyquinoline-5-sulfonamides as possible drugs.

Research Abstract
Fe(II), Fe(III), Co(II), and Ni(II) chelates with three quinolinol sulfonamides have been prepared and characterized. Characterization of the solids so obtained was accomplished by elemental analysis, electronic and ir spectra, and conductivity measurements. It was found that the sulfonamide ligands act as monobasic bidentate ON donors. The bonding sites are ascertained, and the complexes were all six-coordinate assuming a distorted octahedral geometry. It was identified that the metal chelates possess enhanced antibacterial and antifungal activities relative to the free ligands
