The influence of ligand structure on Ni(III)/Ni(II) redoxpotentials has been examined in order to elucidate those factors that lead to unusually low values for this couple, such as are found in [NiFe]-hydrogenases. The compound (Et 4 N) 2 [Ni(pdtc) 2 ] [3, pdtc=pyridine-2,6-bis(monothiocarboxylate) (2−)] is readily prepared and crystallizes in monoclinic space group C2/c. Reaction of 3 with iodine
