Abstract

The NiFe-dinuclear complexes [{Fe(NS3)(CO)2-S,S′}NiCl(dppe)] 1, [{Fe(NS3)(CO)-S,S′}NiCl(dppe)] 2, [{Fe(NS3)(NO)-S,S′}NiCl(dppe)] 3, [{Fe(NS3)(NO)-S,S′}Ni(CH3)(dppe)] 4, [Ni{Fe(NS3)(CO)-S,S′}2] 5 have been prepared using the anions [Fe(NS3)(CO)]− and [Fe(NS3)(NO)]− (NS3 = N(CH2CH2S)33−) as chelate ligands to nickel. Crystal structure characterisation has been carried out on 1, 3 and 5. The spectroscopic properties of the complexes have been measured. Complex 1 is a good structural analogue of the active form of the active site of NiFe-hydrogenase. Complexes 1–5 also show features related to the active sites of the nickel enzymes carbon monoxide dehydrogenase and acetyl-CoA synthase.
