Biological and synthetic catalysts often utilize iron in high oxidation states (+IV and greater) to perform challenging molecular transformations. A coordination complex featuring an Fe(VII) ion has now been synthesized through sequential oxidations of nonheme iron–nitrido precursors.

Ion exchange is a powerful method to access metastable materials for energy storage, but identifying lithium and sodium interchange in layered oxides remains challenging. Using such model materials, vacancy level and corresponding lithium preference are shown to be crucial for ion exchange pathway accessibility.

Hong et al. report 2D perovskite lateral homojunction consists of ordered and disordered phases, achieved by organic cation doping induced phase pinning, built upon which they develop tuneable optical properties under external stimuli and directional exciton diffusion in the homojunctions.

Bis(N-heterocyclic carbene)-borylene complexes are capable of capturing and functionalizing CO₂, but stable single-site-boron-carbon dioxide adducts are rarely reported. Here, the authors report the synthesis of a stable borylene-CO₂ complex as well as the functionalization of the captured CO₂.

The development of new methodologies to convert plastics into fuels without relying on noble metal-based catalysts is desirable. Now it is shown that a layered self-pillared zeolite enables the conversion of polyethylene to gasoline with a selectivity of 99% and yields of >80% without the need to use external hydrogen.

Icosahedral carboranes have long been considered to be aromatic but the extent of conjugation between these clusters and their substituents is still being debated. Here the authors demonstrate carboranes as conjugated bridges in optical functional chromophores.

This study introduces a Eu(II) single molecule magnet that exhibits slow magnetic relaxation at low temperatures. These results highlight the importance of the lanthanide ion’s crystal field in unlocking the magnet-like properties of Eu(II).

Biological and synthetic catalysts often utilize iron in high oxidation states (+IV and greater) to perform challenging molecular transformations. A coordination complex featuring an Fe(VII) ion has now been synthesized through sequential oxidations of nonheme iron–nitrido precursors.

The reduction of molecular species containing arene to alkali metal cation interactions with other alkali metals has been found to contradict the expectation provided by simple considerations of relative reduction potentials.

Despite the growing clinical use of radium in cancer treatments, the fundamental chemistry of nature’s largest +2 cation remains largely unexplored. Now, structural analysis of a radium complex reveals that its behaviour cannot always be predicted from the chemistry of its closest nonradioactive congener, barium.

Since the isolation of a Mg–Mg complex, research on low-oxidation-state s-block chemistry has flourished. An approach to forming metal–metal bonds between Mg and the heavier alkaline earth metals (Ca, Sr and Ba) is now demonstrated. The unusual electronic nature of these compounds could stimulate further discussions of metal–metal bonding.

The study of disordered materials poses numerous challenges, and computational approaches have proved useful to supplement and support structural experiments. Now, an abstract computational model has been used to study the structure of amorphous calcium carbonate, providing mechanistic insights into the emergence of the disordered phase as well as its atomic-level configurations.
