Nickel(II) and zinc(II) complexes of a pyridine ligand bearing a tetrathiafulvalene substituent

  • 300 Accesses

  • 2 Citations


The synthesis, crystal structures, and electrochemical properties of the coordination complexes, NiBr2(ept)2 and ZnBr2(ept)2 (ept = 4,5-ethylenedioxy-3′-(3′-pyridyl)-tetrathiafulvalene) are reported. Both complexes are mononuclear, with monodentate coordination of the ept ligand through the pyridine nitrogen. Cyclic voltammetry measurements for both complexes show a sizable interaction involving the electroactive ept ligand, with stabilization of the oxidized forms of the complexes.
