TLDR
The reaction of benzoic acid with the uranyl(V) complex with the pyridine complex leads to immediate disproportionation with formation of a hexanuclear U(IV) benzoate cluster, a bis-benzoate complex of Uranyl(VI) and water.About:

The crystal chemistry of uranium carboxylates
TL;DR: In this article, a comprehensive review of the crystal structures resulting from the different types of complexation of uranium with carboxylic acid molecules (excepting oxalate ligand) and their classification as a function of the nuclearity of identified building units is presented.

TL;DR: This uranium-based molecular wheel shows an open magnetic hysteresis loop at low temperature, with a non-zero coercive field and quantum tunnelling steps, which suggests that uranium might indeed provide a route to magnetic storage devices.

TL;DR: Three polynuclear thorium(IV) molecular complexes have been synthesized under ambient conditions from reactions of an amorphous Th precipitate, obtained via hydrolysis, with carboxylate functionalized ligands using R-COO(-) ligands to form discrete, neutral molecular clusters.

Molecular Volumes and the Stokes-Einstein Equation.
TL;DR: In this article, a simple notion of the volume of a molecule was adopted to produce an empirical correction factor for the Stokes equation to enable one to apply it to molecules down to two angstroms in radius.
Journal ArticleDOI
Microbial reduction of uranium
TL;DR: In this article, dissimilatory Fe(III)-reducing microorganisms can obtain energy for growth by electron transport to U(VI), which can be much faster than commonly cited abiological mechanisms for reduction.
Journal ArticleDOI
Nanometre-size products of uranium bioreduction.
TL;DR: It is shown that uraninite (UO2) particles formed from uranium in sediments by bacterial reduction are typically less than 2 nanometres across and that the small size has important implications for uranite reactivity and fate.

Oxo ligand functionalization in the uranyl ion (UO22
Skye Fortier,Trevor W. Hayton +1 more
TL;DR: A review of the chemistry of the two oxo ligands of the uranyl ion can be found in this article, where the authors explore the interaction of uranyl oxoxide ligands with Lewis acids, and outline attempts to selectively functionalize the oxo-ligands by chemical means.
