The NiFe-dinuclear complexes [{Fe(NS 3 )(CO) 2 -S,SЈ}NiCl(dppe)] 1, [{Fe(NS 3 3Ϫ ) 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. Results and
