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.

    Finding new thermoelectric materials that can achieve high performance is vital to realizing the potential of future energy harvesting technology. Here, through computation methods, the authors identify two high-performance full-Heusler thermoelectric compounds with high intrinsic band degeneracy.

    Carbonyl complexes have been studied extensively thanks to their rich substitution and redox chemistry, but most homoleptic transition metal carbonyl complexes isolated in the condensed phase are neutral or anionic. Here, the authors isolate two homoleptic carbonyl radical cations in the condensed phase; both 17-electron [Cr(CO)6]•+ salts.

    In actinide chemistry, a longstanding bonding model describes metal-ligand binding using 6d-orbitals, with the 5f-orbitals remaining non-bonding. Here the authors explore the inverse-trans-influence — a case where the model breaks down — finding that the f-orbitals play a crucial role in dictating a trans-ligand-directed geometry.

    Dilanthanide complexes that possess radical bridges exhibit enhanced magnetic exchange coupling, affording molecular magnets with high blocking temperatures. Here, the authors explore a series of dilanthanide-encapsulated fullerenes where the radical bridge is taken to its limit and the role is played by a single unpaired electron.

    Heterometallic clusters have shown promise in catalysis and small-molecule activation, but species comprising uranium–metal bonds have remained difficult to synthesize. Now, facile reactions between uranium and nickel precursors have led to nickel-bridged diuranium clusters supported by a heptadentate N4P3 scaffold. Computational analysis points to an unusual electronic configuration for uranium, U(iii)-5f26d1.

    A two-coordinate monovalent gold complex that features a highly polarized aluminium–gold covalent bond, Alδ+–Auδ−, has been synthesized using a very strongly electron-donating aluminyl ligand. In solution, the complex reacts as a nucleophilic source of gold towards heteroallenes such as carbodiimides and CO2.

    Our understanding of actinide chemistry lags behind that of the rest of the periodic table. A collection of articles in this issue highlights recent progress featuring uranium(VI) dianions bearing four U–N multiple bonds, berkelium(IV) stabilized in solution and delocalization of 5f electrons in a plutonium material.
