چکیده    The synthesis, characterization and diuretic activity of four new biologically active complexes of mg(ii) and vo(ii) with bidentate schiff base ligand acetazolamide–salicylaldimine (l) obtained from the inserted condensation of 5-acetamido-1,3,4-thiadiazole-2-sulphonamide (acetazolamide) with salicylaldehyde in a 1:1 molar ratio have been reported. using this bidentate ligand complexes of mg(ii), mn(ii), fe(ii) and vo(ii) with general formula ml2 have been synthesized. the synthesized complexes were characterized by several techniques using elemental analysis, ftir, electronic spectra, tga, mass, particle size analysis and molar conductance measurements. the elemental analysis data suggest the stoichiometry to be 1:2 [m:l]. the molar conductance measurements suggest non-electrolytic nature of the complexes. infrared spectral data agreed with the coordination to the central metal ion through deprotonated phenolic oxygen and azomethine nitrogen atoms. on the basis of spectral studies, octahedral geometry is suggested for mg(ii), mn(ii), fe(ii) and square pyramidal geometry is suggested for vo(ii) complexes. the pure drug, synthesized ligand and metal(ii) complexes were screened for their antimicrobial activities against eschericia coli, bacillus subtilis, aspergillus niger and aspergillus flavous. the results show that the metal complexes were more active than the ligand and pure drug against these microbial species as expected. the ligand and its mg(ii) complexes was screened for their diuretic activity also.
