How are the [Fe–S] centers in redox enzymes constructed in systems not containing the well‐known structural element of ferredoxin? Title compound 1 , which assembles spontaneously from Fe 2+ ions, 2,2‐(ethylenedithio)‐dibenzothiolate, and sulfur can certainly provide information. The magnetic properties and Fe… Fe distance of H clusters of hydrogenases in the reduced form of the protein agree exactly with those of 1 , but not with those of the known [Fe–S] clusters in the ferredoxins. ∩ = C 6 H 4 .
