    Controlled switching of the spin state of transition metal ions is key in many enzymatic reactions, but difficult to replicate in synthetic systems. Here the authors report on an iron(III) porphyrin with a photochromic axial ligand that, in solution, reversibly switches between low-spin and high-spin upon irradiation with two different wavelengths.

    Achieving control over the thermomechanical properties of functional materials is desirable, yet remains highly challenging. Here, the authors demonstrate continuous negative-to-positive tuning of thermal expansion in two Prussian blue analogues, by varying the concentration of adsorbed CO2.

    Molecules can change their electronic properties when they are adsorbed on substrates, which can be useful for sensing and catalysis. Here, the authors use atomic force microscopy to show that the spin state of an iron complex can be changed upon displacing the molecule to different sites of a nitrogen-doped graphene

    Nitrogenase—whose cofactor consists of a metal–sulfur cluster—catalyzes the production of NH3 from N2, but designing metal–sulfur complexes capable of promoting this conversion remains challenging. Here, the authors report on the activation of N2 by a metal–sulfur cluster containing [Mo3S4Ti] cubes, demonstrating NH3 and N2H4 production.

    The separation of high molecular weight polymers composed of the same number of monomeric units remains highly challenging. Here, the authors show that efficient separation and purification of mixtures of polymers that differ only by their terminal groups can be achieved through polymer threading in metal-organic framework channels.

    Understanding quantum tunnelling of the magnetisation in single-molecule magnets is crucial for their potential application in information storage. Here the authors conduct a field- and temperature-dependent study of the magnetisation dynamics of a dysprosium-based SMM, finding four distinct relaxation processes that dominate in different regimes.

    Stimuli-responsive porous materials are attractive for a range of applications, but each material typically exhibits only one type of transformation. Here, the authors report on a metal–organic material that exhibits six distinct phases as a result of four types of structural transformation in response to different stimuli.

    Spin-crossover molecules offer a potential route towards molecular spintronics, but retaining the bistability of the spin state upon surface deposition is challenging. Here, the authors study the spin-crossover behaviours of an Fe(II) complex deposited on graphite, determining the scale limit at which cooperative spin switching becomes effective.

    While polyhedral boron hydride complexes have found application in a number of diverse fields, the isolation of stable aluminium analogues remains highly challenging. Here, Jones and colleagues demonstrate that reduction of an amidinato-aluminum(III) hydride complex with magnesium(I) dimers affords stable aluminium(I) hydride compounds.

    Owing to the propensity for uranium(III) compounds to undergo disproportionation, uranium-element multiple bonds involving uranium(III) oxidation states remain rare. Here the authors report hexauranium-methanediide rings that formally contain uranium(III)- and uranium(IV)-methanediides supported by alternating halide and arene bridges.

    Paramagnetic metal clusters with large ground spin states often possess attractive magnetic behaviors for information storage or solid-state cooling applications. Here, the authors design a giant {Ni21Gd20} cage, which using quantum monte carlo simulations they predict to possess a spin ground state approaching S = 91.

    The recently introduced glass and liquid states of metal–organic frameworks (MOFs) provide opportunities to design and explore new properties for this class of material. Here, the authors show that a MOF liquid can be blended with another MOF component to produce domain-structured MOF glasses with single, tailorable glass transitions.

    Endowing metal–organic frameworks with both high electrical conductivity and magnetic ordering could make such materials useful for spintronics. Here the authors design a layer-stacking coronene-based 2D MOF that exhibits a semiconducting feature with an electrical conductivity of ~10 S cm−1 at 300 K, as well as ferromagnetism below ~20 K.

    Owing to the energetic nature of N–N bonds, poly-nitrogen compounds are considered promising high energy density materials. Here, the authors synthesize three iron–nitrogen compounds at high pressure, including FeN4, which features polymeric nitrogen chains of [N42−]n units.

    While metal–carbon double bonds are common in transition metal chemistry and catalysis, unsupported uranium–carbon double bonds remain highly challenging to prepare. Here, the authors stabilize and characterize a U=C=U cluster containing unusually short, unsupported double bonds inside an Ih(7)-C80 fullerene cage.
