Approaching Sixfold Chemical Bonding: Metal Dimers MM' Involving Group 4–8 Transition Metals and the Actinides Th–Np. Additive Covalent Radii r6$r_6$

Chemistry – A European Journal, EarlyView.
Twelve‐valence‐electron transition metal dimers MM', like diatomic Mo2, can have nearly sixfold bonds. Values of r6$r_6$ for over 20 elements from Sc to Pu are proposed. ABSTRACT A set of additive covalent radii is fitted to a combination of experimental data, accurate ab initio computations, and more approximate DFT MM' bond lengths, R$R$, with 12 ...

Octupole deformation properties of actinide isotopes within a mean field approach

, 2012
We discuss the octupole deformation properties of many even-even actinide isotopes. The analysis is carried out in the mean field framework (Hartree-Fock-Bogoliubov approximation) by using the axially symmetric octupole moment as a constraint.

Unexpected Products Isolated From Neptunium Halide Syntheses

European Journal of Inorganic Chemistry, EarlyView.
Unanticipated products can crystallize when doing ligand substitution chemistry of NpCl4(DME)2 (DME = 1,2‐dimethoxyethane). Dissolution of NpCl4(DME)2 in CDCl3 can recrystallize the dimer [NpCl3(μ‐Cl)(DME)]2. The presence of hydroxylammonium from oxidation state adjustment can result in the isolation of (NH3OH)2[NpCl6]•3(1,4‐dioxane). The contamination

Yields of rare earth element isotopes in the fission of actinide nuclei [PDF]

Ядерна фізика та енергетика
The paper presents the results of studying the yields of rare earth element (REE) isotopes in the fission of heavy, particularly actinide, nuclei. Mass spectra of REE isotopes (samarium, dysprosium, holmium, ytterbium) were obtained for various fission ...

Fractionation of Milligram Quantities of Gadolinium and Terbium Ions by Annular Free‐Flow Isotachophoresis

ELECTROPHORESIS, EarlyView.
ABSTRACT The fractionation of milligram quantities of gadolinium (Gd) and terbium (Tb) ions is demonstrated using annular free‐flow isotachophoresis (ITP) with ammonium as the leading ion and hydronium as the terminating ion, and α‐hydroxyisobutyric acid (HIBA) and acetate as lanthanide complexing ligands.

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

Small, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

High Spin Iron–Phosphinidene and Arsinidene Complexes With Attenuated Metal–Ligand Multiple Bond Character

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Unusually low metal–ligand bond orders are observed in high spin iron(II) pnictogenidene (PH2– and AsH2–) complexes. Electronic structure analysis provides evidence for multiconfigurational character that attenuates the metal–ligand multiple bond character normally that is typically associated with pnictogenidene ligands. These complexes can be used to
