METAL COMPLEXES OF SOME THIOCARBOHYDRAZONE LIGANDS: SYNTHESIS AND STRUCTURE
Azza Aly;
Abstract
The synthesis, structure, physico-chemical investigation and biological studies of some metal complexes of
thiocarbohydrazone ligands are described. The ligands were obtained by condensation of N,N0-thiocarbohydrazide
with carbonyl compounds such as 2-hydroxyacetophenone or 5-chlorosalicylaldehyde. A variety
of binuclear or mononuclear complexes were obtained with the ligands in mono-, bi- and/or tri-deprotonated
forms. The bonding sites are the azomethine nitrogen atom, phenolic oxygen atom and thiol sulfur atom. The
metal complexes exhibit either tetrahedral or octahedral structures. Preliminary antimicrobial screening
showed that the ligands and their metal complexes possess antimicrobial activity towards bacteria and fungi.
