Andrew Boggiano

I've heard this in multiple fields and can't say it is consistent with anyone I know who recently completed a PhD's experience

Congrats!

The color is impeccable

Very nice!!

Dear US researchers: break the outrage addiction. I survived the besieging of science. So can you. As I watch US researchers respond to threats against science, I’m reminded of when scientists in Brazil navigated a similar storm.

I have wondered why current admin is not interested in bolstering scientific funding given how much they seem to care about staying competitive globally... Seems like it would be a pretty convincing argument

😂 I've written this footnote before, specifically for reviewer #2

U4+/5+/6+ in a Conserved Pseudotetrahedral Imidophosphorane Coordination Sphere | Inorganic Chemistry pubs.acs.org/doi/10.1021/... La Pierre and co-workers @InorgChem #uranium #456cationic #imidophosphorane #pseudotetrahedral

U4+/5+/6+ in a Conserved Pseudotetrahedral Imidophosphorane Coordination Sphere While several ligand systems support uranium across a range of oxidation states, spanning more than two oxidation states in a conserved coordination geometry is uncommon among structurally authenticated complexes. Imidophosphorane ligands significantly stabilize high-valent lanthanide and actinide complexes. Here, we report a series of homoleptic uranium imidophosphorane complexes, spanning the +4, +5 and +6 oxidation states in a four-coordinate pseudotetrahedral ligand field. The +6 oxidation state is accessible using a mild ferrocenium oxidant, yielding a rare example of U6+ in a pseudotetrahedral coordination environment. As the formal oxidation state increases, the U–N distances gradually contract, consistent with the Shannon ionic radii of U4+/5+/6+. Compared to reported complexes, the short U–N distances observed in the U6+ complex are more comparable to dianionic imido ligands than monoanionic amido ligands.

My new study featuring a series of uranium in the +4/+5/+6 oxidation states.

I've been very intrigued by the prospect of isolating this unusual tetrahomoleptic U6+ di BArF salt for some time, and am happy to share it in IC! s/o to my co authors!

Isolation of Inner-Sphere Aquo Complexes of Samarium(II) The cis-anti-cis and cis-syn-cis isomers of [Sm(dicyclohexano-18-crown-6)(H2O)2]I2 exhibiting trans water molecules bound to the Sm2+ ion have been isolated and characterized. Sm2+ possesses an electrochemical potential sufficient for water reduction, and thus these complexes add to the recent body of evidence that the oxidation of Sm2+ by water can operate by a mechanism that is not straightforward. These complexes are obtained by the direct addition of stoichiometric amounts of water to solutions of the respective Sm(dicyclohexano-18-crown-6)I2 isomers under an inert atmosphere. The parent complex, Sm(dicyclohexano-18-crown-6)I2, lacking coordinating water molecules can be obtained through rigorous exclusion of water. It was determined that the bulky cyclohexano-substituents deter intramolecular interactions between [Sm(dicyclohexano-18-crown-6)(H2O)2]I2 complexes and slow the oxidization of the metal centers. The extent of the stability of these complexes to the presence of water has been further probed through cyclic voltammetry, where it was found that the redox potential of both isomers of [Sm(dicyclohexano-18-crown-6)(H2O)2]I2 maintains quasi-reversible behavior with a 50,000-fold excess of water to Sm2+ in solution with the cis-syn-cis complex being quasi-reversible at even higher concentrations of water. Solution-phase spectroscopy of these complexes in acetonitrile shows a corresponding hypsochromic shift of the Sm2+ 4f → 5d transition typically observed in the visible region from Sm2+ complexes. The crystalline compounds obtained in this study support solid-state spectroscopic trends observed from other Sm2+ crown-ether complexes containing iodide counterions, wherein the proximity of the iodide ions to the metal center determines whether the complex can exhibit 4f → 4f photoluminescence.

This article was years in the making. Did you think water could coordinate to Sm(II) without being reduced? Well it can. Congratulations Todd! #Chemsky #Bluesci #samarium #rareearths #fblockrocks
