Nickel(II) complexes bound to an [Fe₄S₄] cluster via bridging thiolates:synthesis and crystal structure of model compounds for the active site of nickel CO dehydrogenase

Frank Osterloh, Wolfgang Saak, Detlev Haase and Siegfried Pohl

[NiL][L =^�SCH₂CH₂N(Et) CH₂ CH₂ CH₂N(Et) CH₂ CH₂S^�] 1 reacts with [Fe₄S₄I₄]^2� to afford [(NiL)₂Fe₄S₄I₂] 3; in 3 the two fragments of 1 are doubly bridged via�-sulfur of L to iron atoms of the [Fe₄S₄] core.
