  • Collisions between atoms and molecules are largely understood; however, our understanding of collisions between two molecules is lacking because they are significantly harder to study, Now, correlated rotational excitations have been observed in inelastic collisions between NO and O2 molecules. It is shown that the energy-gap law that governs atom–molecule collisions does not generally apply to bimolecular excitation processes.

  • Cation–anion exchange between dimers to prepare mixed aggregates with Mg–Ae (alkaline earth) bonding (Ae = Mg, Ca, Sr, Ba) is reported. Considerable electron transfer from the (BDI)Mgˉ anion (BDI, β-diketiminate) to Ae and Na atoms is observed, and the reactivity of these electron-rich complexes with Na–Mg–Ae bonding is discussed.

  • Following the building principles of crown ethers for cation encapsulation, inverse crowns are rings of metals that bind anions. Now a redox-active inverse crown ether featuring Na+ cations and Mg0 has been shown to reduce epoxides, N2O, S8 or O2 by combining anion complexation by the ring of metal cations with the reducing power of Mg0.

  • Elemental iron turns alkaline-earth metal complexes into highly active catalysts for the hydrogenation of alkenes, alkynes, imines and arenes. The proposed mechanism combines homogeneous catalysis by a soluble main group metal hydride complex with heterogeneous catalysis at the iron surface.

  • Hydrogenation is one of the most common catalytic processes on both laboratory and industrial scales, and typically is carried out with a noble metal catalyst. Here, the authors show that alkaline earth metal amides are capable of hydrogenating imines under mild conditions.

  • Unravelling the formation of binary nanocrystal phases is challenging. Here, by combining in situ small-angle X-ray scattering and molecular dynamics simulations, we show that AlB2 and NaZn13 superlattices undergo classical homogeneous nucleation consistent with the presence of short-range attractive interactions guiding the crystallization process.

  • Particle fusion can improve signal-to-noise ratio in single molecule localization microscopy, but is limited by structural heterogeneity. Here, the authors demonstrate an unsupervised classification method that differentiates structurally different DNA origami structures without prior knowledge.

  • Although Grignard reagents containing the heavier alkaline-earth metals have been explored, they have always been an academic oddity. New synthetic routes such as ball milling and novel concepts for application may result in exploitation of the unique reactivity of calcium, strontium and barium reagents.

  • Stereodynamics describes how the vector properties of molecules affect the probabilities of specific processes in molecular collisions. Measurements of irregular diffraction patterns for NO radicals colliding with rare-gas atoms reveal a previously unrecognized type of quantum stereodynamics and a ‘propensity rule’ for the magnetic quantum number (m) of the molecules.
