Selective methane oxidation by molecular iron catalysts in aqueous medium
Methane can be oxidized to methanol using N-heterocyclic carbene-ligated FeII complexes, in which the hydrophobic cavity captures the methane substrate from an aqueous solution and releases the hydrophilic methanol product back into the solution.

The active site of low-temperature methane hydroxylation in iron-containing zeolites
Iron-containing zeolites have an exceptional ability to convert methane into methanol, but their active site have been hard to study; now, magnetic circular dichroism has been used to explore the reactive species, providing a technique that should be generally applicable, and revealing the value of constraining active sites within a lattice to improve catalyst functionality.

A pentanuclear iron catalyst designed for water oxidation
A complex containing five atoms of iron is shown to be a highly efficient and robust water oxidation catalyst owing to the presence of redox flexibility, which enables charge accumulation and electron transfer, and the presence of adjacent active sites that enables intramolecular O–O bond formation.

Four-electron deoxygenative reductive coupling of carbon monoxide at a single metal site
The environmental and geopolitical problems associated with fossil fuels might be alleviated if it were possible to produce synthetic multicarbon fuels efficiently from single-carbon feedstocks; here, a molybdenum compound supported by a terphenyl–diphosphine ligand is used to convert carbon monoxide into a metal-free C2O1 fragment, with the ligand both serving as an electron reservoir and stabilizing the different intermediate species.

Multiple complexation of CO and related ligands to a main-group element
Transition metal–ligand fragments are often able to bind and release several carbon monoxide molecules, such as the catalysts used in industrial-scale acetic acid synthesis and the active sites of hydrogenase enzymes, but main-group elements have never shown an ability to bind more than one carbon monoxide molecule; here a boron-based compound stable to moisture and air is synthesized and shown to contain multiple carbon monoxide units bound to the central boron atom.

X-ray analysis on the nanogram to microgram scale using porous complexes
Absorption of target molecules into a porous matrix permits single-crystal X-ray diffraction analysis of the ‘guest’ molecules, avoiding the need to obtain them in single-crystal form and making analysis possible using as little as 80 nanograms of sample.

Charge order and three-site distortions in the Verwey structure of magnetite
X-ray diffraction is used to show that the structural distortion of magnetite below 125 kelvin is to a first approximation caused by charge ordering of its constituent iron ions, but that the localized electrons are distributed over three iron sites to form ‘trimeron’ quasiparticles.
