Imines derived from different sulphadrugs and heterocyclic ketones and their Μη (II) complexes have been synthesized and characterized by their elemental analysis, molecular weight determinations, conductance and magnetic measurements. A high spin tetrahedral geometry around this metal ion has been proposed on the basis of magnetic and spectral studies. The unimolar and bimolar reactions of hydrated manganese acetate and chloride with monobasic, bidentate heterocyclic ligands resulted in the formation of the coloured solids which are soluble in DMF and DMSO. The molecular weight determinations indicate them to be monomers and their conductivity measurements in dry DMF show them to be non-electrolytes. All the ligands and their corresponding complexes have been screened for their fungicidal, bactericidal and nematicidal activities.Brought to you by | Purdue University Libraries Authenticated Download Date | 5/30/15 10:44 PM Vol. 9, No. I, 2003Biologiocally potent heterocyclic sulphonamide imines and their manganese(II) complexes
