  • The mechanism by which the [NiFe4S4] cluster of carbon monoxide dehydrogenases (CODHs) catalyses CO2 reduction is poorly understood. Now the structures of all catalytically relevant states of a CODH are solved, revealing the dynamics of the cluster during turnover and the role of Ni in CO2 activation.

  • Carbon- and silicon-based triplet diradicals with two unpaired electrons are proposed as intermediates in organic and organometallic reactions but their isolation is challenging. Now, isolable 1,3-disilapyrroles are reported to act as organosilicon-based delocalized triplet diradicals and mediate the cleavage of the CO triple bond and C(sp3)–H bond activation.

  • The multistep incorporation process of the catalytic NiFe(CN)2(CO) cofactor into [NiFe]-hydrogenase was deciphered by isolating key maturation intermediates, which were characterized by biochemical and a variety of spectroscopic techniques.

  • The structure and function of the MCR activation complex from Methanococcus maripaludis were revealed, demonstrating its ATP-dependent ability to activate MCR and form methane while uncovering a unique electron transfer pathway involving iron–sulfur clusters similar to the nitrogenase cofactor intermediates.
