Abstract

The aim of this work was the synthesis of novel ferrocenyl chalcogenide ligands and their late transition metal complexes, and the study of relevant electrochemistry to provide information for exploring their potential application in a new type of electrochemical sensor. The introduction reviews fou...

Four compounds' structures have been determined by X-ray crystallography: FcSe(CH2)3SeFc, FcSe(CH2)3Se(CH2)3SeFc, difcSe4 and FcSeCH2C6H4CH2SeFc.
