Synthesis of a BEDT-TTF bipyridine organic donor and the first FeII coordination complex with a redox-active ligand.
Résumé
The synthesis of the new ligand, BEDT-TTF-bpy [4,5-ethylenedithio-4',5'-(4'-methyl-2,2'-dipyrid-4- ylethylenedithio)-tetrathiafulvalene] is reported. The first FeII coordination complex, namely [Fe(NCS)2(BEDT-TTF-bpy)2], with this redox-active ligand is obtained. Magnetic measurements and Mossbauer spectroscopy revealed the coexistence of high-spin and low-spin FeII species with a ratio of 40:60 in this compd. The complex also was studied using cyclic voltammetry.
