Meteoritic organometallic compounds compared to active sites. a [FeII(CN)5(CO)]3− (boxed) and active-site structure of [NiFe]-hydrogenase from Desulfovibrio gigas (1FRV). b [FeII(CN)4(CO)2]2− (boxed, cis form shown) and active-site structure of [FeFe]-hydrogenase from Clostridium pasteurianum (3C8Y). Regions that are shaded blue indicate structural similarity. A bridging ligand between metals is not shown for clarity
