Summary
The reactions of a variety of divalent transition metal ions with 3-methyl-5-(2-hydroxypheny)-, 3-methyl-5-(2-thienyl)-and 3-methyl-5-(2-furyl)-1,3,4-thiadiazolidine-2-thiones (htt, ttt and ftt, respectively) are accompanied by opening of the thiadiazolidine ring and rearrangement to the corresponding Schiff base (Hhts, Htts and Hfts, respectively) with the concomitant formation of complexes of the general formulae, [M(hts)] (M=Ni, Cu, Zn or Pd), [M(hts) (py)] (M=Ni, Cu), [Co(Hhts)hts)], and [ML2] (M=Ni, Cu, Zn or Cd); L=tts or fts). The complexes have been characterised by physico-chemical and spectroscopic methods. The fungitoxicities of the corresponding Schiff base metal complexes have been investigated.
