" electrode, nickel-iron hydrogenase catalyzes hydrogen oxi- Darensbourg, Tom Rauchfuss, and Chris Picket saw a dation at a diffusion-controlled rate that matches the rate simple diiron organometallic molecule as an obvious mimic achieved by platinum. However, said Darensbourg, there are of the iron hydrogenase active site.

flexibility is in the Fe(CO) 3 units on each end of the diiron The diiron organometallic molecule has several attractive complex, which shows intramolecular CO site exchange features, such as the flexibility associated with the iron also detectable in variable temperature NMR experiments.

From the DFT study Thomas Rauchfuss, University of Illinois at Urbana various parameters can be extracted, including unpaired introduced his presentation by explaining that there is a lot spin density. Hall and Thomas found that the unpaired spin of organometallic chemistry occurring in nature.

instead of using a complicated dithiolate, he is using a simple ethane dithiolate and replacing complicating cyanides and Noninnocent Ligands the iron-4 sulfur-4 cluster with phosphine ligands. It is a robust system, and very ordinary old Wilkinson-style ligands Rauchfuss's team is working on noninnocent ligands, are used to support this complicated chemistry.

He said that there needs to be a structural tool to M agnesium requires five ligands, so the fifth ligand can be present specific information. The Advanced Photon Source, one of the oxygen atoms of a corresponding nearby chloro- the brightest X-ray source in the country, at Argonne National phyll, such as the carbonyl group or a bridging ligand.
