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 Fe2+ 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. ∩ = C6H4.
