Such ligands have been designed for the synthesis of polymetallic coordination complexes. They were synthesized by the condensation reaction between aldehydes and substituted thiosemicarbazides in alcohol, using acetic acid as a catalyst. To determine the structure, composition and purity, the products were characterized using nuclear magnetic resonance spectoscopy, mass spectroscopy and elemental analysis.robis-thiosemicarbazonesynthesis methodsNMR characterizationpolymetallic complexesArticle
