Chemical bonding

Chemical bonding refers to the attraction between atoms and can come in several different types with varying strength. It allows the formation of substances with more than one atomic component and is the result of the electromagnetic force between opposing charges. Understanding the making and breaking of bonds is at the heart of chemistry.

    Little is known about interactions between two antiaromatic molecules. Here, the authors synthesised a cyclophane, in which two antiaromatic porphyrin moieties adopt a stacked face-to-face geometry with a distance shorter than the sum of the van der Waals radii of the atoms involved.

    The study of main group complexes remains important to our fundamental understanding of main group element bonding and properties. Here the authors isolate and spectroscopically characterize a series of 8-coordinated alkaline earth metal–dinitrogen complexes M(N2)8 (M=Ca, Sr, Ba) in a low-temperature neon matrix.

    Beryllium in inorganic compounds is usually coordinated to four oxygen atoms, but higher coordination numbers have been predicted. Here the authors observe a pressure induced stepwise transition in CaBe2P2O8 where Be coordination changes to trigonal-bipyramidal and octahedral, implying that d orbitals are not mandatory for high coordination.

    High-throughput computation is especially useful for materials screening where synthesis is challenging. Here, it is used to construct a stability map of ternary nitrides, allowing discovery of stable compounds and providing insight into principles that govern nitride stability.

    Studying the electronic structures and spin transitions of synthetic heme analogs is crucial to advancing our understanding of heme enzyme mechanisms. Here the authors show that a Co(II) porphyrin complex undergoes an unexpected spin state transition upon deprotonation of its axial imidazole ligand.

    Gold — long presumed to be an inert metal — has been increasingly shaking this image over the past couple of decades, mostly through electrophilic behaviour. Now, a two-coordinate gold complex has been shown to exhibit nucleophilic reactivity, with the insertion of CO2 into its polarized Auδ−–Alδ+ bond.
