✦ Synopsis

A new ferrocene-containing thio-Sehiff base, S-methyl-fl-N-(ferrocenyl)methylenedithiocarbazate (FTSBH), was prepared by the condensation of formylferrocene with S-methyldithiocarbazate. Its rare earth complexes [Ln-(FTSB)3 ] (Ln = lanthanide) were also obtained, by the reaction of LnC13 with the thio-Schiff base derivative in EtOH. The ligand coordinates to lanthanide(III) in its thioenol form. The complexes are nonelectrolytes in DMF, and are more thermostable than the ligands due to the formation of chelate rings.
