Synthesis and structure of a thiolate-bridged nickel–iron complex: towards a mimic of the active site of NiFe-hydrogenase

Abstract

The reaction, under carbon monoxide, of [Fe(NS3)(CO)]– [NS3 = N(CH2CH2S)33–] with [NiCl2(dppe)] gives the structurally characterised dinuclear thiolate-bridged complex [{Fe(NS3)(CO)2-S,S′}NiCl(dppe)], which has structural features similar to those of the active site of NiFe-hydrogenase.
