Syntheses, characterization and properties of rhenium(I) tricarbonyl complexes based on tetrathiafulvalene substituted naphthyridine ligands

Abstract: New amide functional tetrathiafulvalene ligands containing naphthyridine moiety (L 1 –L 3 ) were synthesized. Further coordination reactions of these ligands with Re(CO)5Cl afford three interesting rhenium tricarbonyl complexes, ClRe(CO)3(L). Crystal structures of ClRe(CO)3(L 1 ) (1) and ClRe(CO)3(L 2 ) (2) have been determined. Electrochemical and spectroscopic properties of all compounds are investigated. [Copyright &y& Elsevier]
