Metalloporphyrins have a variety of roles in nature, including catalysis and the transport of respiratory gases, and many of these involve the binding of diatomic molecules. Now, the interaction of carbon monoxide with simple iron- and cobalt-porphyrins has been studied at the single-molecule level, revealing a surprising binding scheme.
