Synthesis, X-ray structure and electrochemical characterisation of a binuclear thiolate bridged Ni–Fe–nitrosyl complex, related to the active site of NiFe hydrogenase

Abstract

[NiL] 1 (L = N,N′-diethyl-3,7-diazanonane-1,9-dithiolate) reacts with [Fe(CO) 2 (NO) 2 ] 2 to afford [Ni(L)Fe(NO) 2 ] 3, in which a Ni II ion and a nitrosylated Fe - II centre are bridged via two µ-S atoms from the chelating ligand.
