  • Möbius aromaticity extends the concept beyond Hückel systems, but examples are quite uncommon and typically display twisted topologies. Here the authors describe planar Möbius aromatic complexes, which contain 16 and 18 valence electron osmium centres.

  • Although complexes with monatomic zero-valent main group centers have been reported, diatomic zero-valent complexes are rare, and previously reported examples were stabilized by either carbene or silylene ligands. Here, the authors report the isolation of a diatomic E(0)-E(0) (E = Sn, Pb) species supported by two [N{CH₂CH₂NPiPr₂}₃Sn] fragments.

  • The isolation of compounds featuring an actinide–actinide bond is challenging. Now a well-defined Th(III) dimer with a Th–Th two-centre one-electron (2c-1e) σ bond and a 2c-1e π bond is synthesized. Theoretical and magnetic studies show that the open-shell singlet ground state and the two formal Th(III) centres exhibit strong antiferromagnetic coupling.

  • Pentalyne — a bicyclic anti-aromatic molecule that contains a strained five-membered ring — is a challenging synthetic target. Incorporation of an osmium centre has been shown to stabilize such features and enable the preparation of two osmapentalyne derivatives. Despite featuring the smallest angles observed so far at a carbyne moiety, these molecules benefit from Möbius aromaticity and reduced ring strain.

  • Chiral binaphthols have been staples as ligands in homogeneous asymmetric catalysis for decades, inducing chirality in transformations of the substrate by noncovalent interactions between the catalyst microenvironment and ligand. Here, the authors demonstrate that the chiral-at-metal stereoinduction mode is also a viable method for stereoinduction when using this ligand class.

  • The synthesis and isolation of uranium(VI) nitride complexes remains challenging. Here, the authors report an example of transition metal (TM) stabilized U(VI) nitride complexes, generated via photolysis of azide-bridged U(IV)-TM precursors.

  • 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.

  • Coordination complexes based on polydentate ligands that contain both nitrogen and carbon ligating atoms are ubiquitous, but design of those with planar cores remains challenging. Here the authors show that complexes with planar CCCN, CCCCN and NCCCN cores can be accessed by modification of the coordinating atoms in CCCC core complexes.

  • While chemical bonding between carbon and the d- and p-block elements is relatively well-studied, that between carbon and the f-block elements remains comparatively poorly understood. Here, the authors synthesize a series of uranium−carbone complexes in which carbon forms an unprecedented double dative bond to uranium.
