Highlights with ‘Relativistic DFT’

Fast Intrinsic Emission Quenching in Cs4PbBr6 Nanocrystals

Cs4PbBr6  belongs to the family of 0D metal halides, with separated and isolated [PbBr6]4- octahedra. These systems, in both nanocrystal and bulk forms, have been reported as being either non-emissive or green-emissive at room temperature...

Exceptional Uranium-Nitride Triple Bond Covalency confirmed with NMR

The Liddle group continues to deeply probe the unusual nature of the actinide-main group bonds through combined experimental and computational studies. We previously highlighted the first U-N triple bonds along with a number of other...

Transformable Polyoxometalates, Sustainable Nanoelectronics

Molecular metal oxides, or more notably polyoxometalates (POMs) are being researched for over a century. Their structure benefits from very high stability, whose inherent connectivity relies predominantly on metal-oxygen bonds. Theoretical insights into the bonding...

Aqueous speciation of polyoxometalates

Polyoxometalates self-assembly in aqueous solution is still a subject under study. This is due to the high complexity that involves describing all the chemical equilibria. Experimental techniques investigated this matter with great successes yet more...

Investigating the mechanisms for methylmercury poisoning

Methylmercury is an electrophilic toxicant present in the list of the ten most chemicals of major public health concern substances provided by the WHO. Its capacity of binding to biologically relevant thiols and selenols, disrupting...

Strong covalent Th-Th bond inside C80

An unprecedented thorium-thorium bond has been characterized inside the icosahedral Ih(7)-C80 carbon cage. The single-crystal X-ray diffraction of Th2@Ih(7)-C80 unambiguously determined that the two encapsulated Th atoms are separated by 3.816 Å, accurately reproduced by DFT...

Is Metallophilicity Really Attractive?

Metallophilicity (M-M’ closed-shell interaction) was discovered in the early 1970s, when close metal-metal contacts were observed extensively in d10-d10 (AuI-AuI, AgI-AgI, CuI-CuI, Pd0-Pd0, Pt0-Pt0) and d8-d8 (RhI-RhI, IrI-IrI, PtII-PtII, PdII-PdII) transition metal complexes. Metallophilicity is...

Unraveling the stability of ThO2 nanoclusters

In the field of nanotechnology, the ultimate goal is to produce nanostructures with specially tailored properties that contrast with those in the bulk. Actinide dioxide nanomaterials play an increasingly important role in the design of...

Photochemical water oxidation by uranyl nitrate

Uranyl coordination chemistry enables a wide range of chemical transformations which have been recently reviewed by Arnold et al. [Chem. Rev. 2019, 10595]. Especially the photochemical properties of uranyl complexes are promising.Among all the photo-assisted...
