A convenient ligand exchange pathway to [2Fe–2S] ferredoxin analogues†
Abstract
The benzanellated analogues (NEt4)2[Fe2S2(indolate)4] (2) and (NEt4)2[Fe2S2(carbazolate)4] (3) of the previously reported parent (NEt4)2[Fe2S2(pyrrolate)4] cluster (1) were synthesized and characterized spectroscopically. In contrast to 1 and 3, compound 2 can be applied as a versatile precursor in
