Structural Studies of Transition Metal Complexes with 4,5-Bis(2-pyridylmethylsulfanyl)-4‘,5‘-ethylenedithiotetrathiafulvalene: Probing Their Potential for the Construction of Multifunctional Molecular Assemblies

Three divalent transition metal complexes of 4,5-bis(2-pyridylmethylsulfanyl)-4‘,5‘-ethylenedithiotetrathiafulvalene have been
prepared and crystallographically characterized. The isostructural
Co(II) and the Ni(II) complexes show octahedral geometries around
the metal ions with the coordination sites occupied by the pyridyl
nitrogen atoms and the thioether sulfur atoms of the ligand and
cis coordination of the halide ions. Cyclic voltammetry reveals that
the complexation leads to a small anodic shift in the first oxidation
potential of the TTF system.
