Synthetic Metallodithiolato Ligands as Pendant Bases in [FeFe], [Fe[Fe(NO)]], and [(μ-H)FeFe] Complexes.

The development of ligands with specific stereo- and electrochemical requirements that are necessary for catalyst design challenges synthetic chemists in academia and industry. The crucial aza-dithiolate linker in the active site of [FeFe]-Hase has inspired the development of synthetic analogues that utilize ligands which serve as conventional σ donors with pendant base features for H binding and delivery. Several MNS complexes (M = Ni, [Fe(NO)], [Co(NO)], etc.
