Synthetic, stereochemical and biological aspects of organoantimony(III) derivatives of thio-imines

Abstract Diphenylantimony(III) derivatives of monobasic bidentate thiosemicarbazones derived from heterocyclic aldehydes and ketones have been synthesized and characterized by elemental analyses, molecular weight determinations and conductance measurements. The stereochemical features of these newly synthesized complexes have been discussed in terms of IR, 1H NMR and 13C NMR spectral data. Some representative ligands and their metal chelates have also been screened for their antifungal activity.
