Huge congratulations Darren and team!

Our latest paper is out in Nature Comms describing the first Fe(I)-ketyl radical complex. Congratulations to Laura, Ryan, Adam and our collaborator David Robinson from Nottingham Trent.

Over 2.5 years @reecelisterroberts.bsky.social has been working on isolating a range of 4-atom nitrogen chain radical anions! Now published in @natchem.nature.com! @oxfordchemistry.bsky.social @manchester.ac.uk @ukri.org @erc.europa.eu www.nature.com/articles/s41...

Congrats Meera and co. This is ace - and beautiful EPR spectra too!

Very cool work! Congrats

Matt, Imogen and Mickey’s paper detailing the synthesis and reactivity of the first neutral Al(I) trimer is out now in @natcomms.nature.com! Check it out here along with @mattdv-t.bsky.social’s ‘behind the paper’ article!

Excited to show our latest preprint “Uranocenium – The bis-[8]annulene Uranium Cation”.

Uranocene is oxidised to uranocenium cation both chemically, and electrochemically, with reversibility comparable to ferrocene.

This derives from an unusual electronic structure.

Isolable f-element diphosphene complexes by phosphinidene group transfer and coupling at uranium - Nature Communications The parent diphosphene molecule is of fundamental interest, but its reactive nature renders it challenging to isolate, and current metal-stabilized derivatives are limited to complexes of p-/d-metals....

Check out our work on the isolation of elusive f-element diphosphene (HPPH) complexes, the first heavier Group 15 analogue of f-element diazenes (HNNH) that were first reported over thirty years ago.

@john-seed.bsky.social collected some gorgeous magnetic data - as always! In fact the Tb(III) data suggested a well-isolated paramagnetic pseudo-doublet spin-orbit ground state which has led to some spin-off work so stay tuned!

Synthesis, Redox Chemistry, and Electronic Structures of Bis-di(silylamido)silane f-Element Complexes We report the synthesis and characterization of pseudo-tetrahedral f-element complexes bearing the sterically demanding bidentate di(silylamido)silane ligand, {Me2Si(NSiiPr3)2}2– (Me2SiN†N†). Two equi...

Y'all wanted some EChem? Check out our contribution in InorgChem @acs.org towards tetravalent lanthanides, with @conradgoodwin.bsky.social, @john-seed.bsky.social, in collaboration with @gen-chem.bsky.social + @peremiro.bsky.social for calculations!

Uranium-stibinidiide, -stibinidene, and -stibido multiple bonds and uranium-nitride formation from multimetallic diuranium-distibene-mediated dinitrogen cleavage Nature Communications - Although uranium-nitrogen multiple bonding is well developed, there are far fewer uranium-phosphorus and -arsenic multiple bonds, and none for antimony, even in...

Great collaboration between the Universities of Manchester and Marburg to bring uranium and antimony together. @john-seed.bsky.social‬, ‪@unimarburg.bsky.social‬,
Special congratulations to Rebecca, Kevin and Nick for their synthetic work.

Huge (!) congratulations to Becky and Jingzhen for some tremendous synthetic chemistry, and for the former's 1st first author publication, and to all authors who helped contribute to this work - especially @haenisch-group.bsky.social at @unimarburg.bsky.social. Please read and enjoy!

There are no examples of uranium-antimony multiple bonds, even under spectroscopic scenarios. Until now. Check out our work on U-Sb bonds spanning single, double, and pseudo-triple bonding interactions. Out now in @natcomms.nature.com ! www.nature.com/articles/s41...

Nobelium becomes heaviest element with identified compounds Complexes containing hydroxide, water and dinitrogen ligands detected as researchers probe chemistry on the edge of the actinide series

Complexes containing nobelium were created as part of new research into the chemistry of the actinide series.

Thanks a lot for the support Dave! 😄

Thank you!

I think I’ll be using that analogy from now on. Thanks a lot - glad you like it!

Delighted to have received the @manchester.ac.uk Chemistry department Outstanding Achievement Award for our work on exalted diamagnetism in trithorium superatoms. Hugely grateful to the team of people who contributed to this work and all those who supported yesterday during the award symposium 😃

Magnetic hysteresis up to 73 K in a dysprosium cyclopentadienyl-amide single-molecule magnet Single-molecule magnets (SMMs) based on dysprosocenium cations, [Dy(CpR)2]+ (CpR = substituted cyclopentadienyl), have set record effective energy barriers to magnetic reversal (Ueff) and temperatures...

Jek leads our latest preprint in @chemrxiv.bsky.social with the @nfchilton.bsky.social group on a mixed axial dysprosium amide-cyclopentadienyl single-molecule magnet (SMMs). We find similar high-temperature soft hysteretic properties to dysprosium bis(amide) SMMs.

Huge congratulations Dave, Nick, Gemma and team! 🎉🥳

Soft magnetic hysteresis in a dysprosium amide–alkene complex up to 100 kelvin - Nature A dysprosium amide–alkene complex shows soft magnetic hysteresis loops up to 100 kelvin, arising from the high charge density of the amide ligands and the structural role of the pendant alkene.

Delighted to announce the publication of our work in @nature.com, in collaboration with @nfchilton.bsky.social's group, on a dysprosium compound with magnetic memory at 100 Kelvin. Congrats to all authors inc. @gemmagransbury.bsky.social, @jeffjefftyjeff.bsky.social

Breaking Bonds at Tin(II): Reductive or Oxidative Addition? Here, the addition of H–H, Be–Be, B–B, and B–H bonds to SnII is studied by experimental and theoretical means. We report the first examples of B–B and Be–Be bond additions to a main group metal centr...

Breaking bonds at tin(II)! We've had a look at the spectrum of bond addition reactions, from reductive (Be-Be) to oxidative (Cl-Cl), and everything in between (B-B, B-H, H-H)

Good luck with everything Gemma!

Trithorium superatom confounds with its unexpected and ‘mind-blowing’ diamagnetism Nanocluster behaves like a 'super alkali-metal'

The first superatoms made using actinides ever created are adding a new dimension to one of the strangest chemical phenomena.

Thanks a lot Lisa. Glad you like it!

Thanks so much! 😃

Thanks Andrew. Absolutely! 🤝🏻

This has been a mountain of work from all authors, and impossible without the contributions of the whole team. Eternally grateful to have such talented, knowledgeable, and collaborative colleagues here in Manchester. Please read and enjoy! @uniofmanchester.bsky.social

However, in external applied magnetic fields, these S = 1/2 clusters are diamagnetic (!) as the valence delocalisation enables exalted diamagnetism, which overwhelms the intrinsic paramagnetic character, experimentally evidencing actinide open-shell superatomic character.
