Crystal structure diversity in the bis hydrotris-(3,5-dimethylpyrazolyl)borate iodouranium(III) complex: from neutral to cationic forms

Marinella Mazzanti

The iodouranium(iii) complex with two hydrotris(3,5-dimethylpyrazolyl) borate ligands is shown to adopt three closely related forms in the solid state. In addition to the previously reported structure for [U(TpMe2) 2I], in which one of the pyrazolyl rings ...

Is Y-2(B12H12)(3) the main intermediate in the decomposition process of Y(BH4)(3)?

Dodecaborates, i.e. the [B12H12]2- containing species, are often observed as main intermediates in the hydrogen sorption cycle of metal borohydrides, hindering rehydrogenation. In the decomposition process of Y(BH4)3, yttrium octahydrotriborate, i.e. Y(B3H ...

Luminescent latex particles loaded with anionic lanthanide complexes: a versatile platform for multicolour optical coding

Marinella Mazzanti

Luminescent polymer latexes loaded with lanthanide complexes have been synthesized by miniemulsion polymerization. A self-assembled europium complex was embedded into poly(methyl methacrylate) nanoparticles without covalent linking and compared to a commer ...

Low-energy non-linear excitations in sphere packings

Matthieu Wyart

We study theoretically and numerically how hard frictionless particles in random packings can rearrange. We demonstrate the existence of two distinct unstable non-linear modes of rearrangement, both associated with the opening and the closing of contacts. ...

Living in interesting times

Béatrice Ferrari

Interactions of transmembrane (TM) helices play a key role in many cell processes. The configuration and cross angle these helices adopt are traditionally attributed to specific residue interactions. We present a different approach, in which specific resid ...

Highly relaxing gadolinium based MRI contrast agents responsive to Mg2+ sensing

Marinella Mazzanti

A Gd complex based on a polyphosphonated pyridyl ligand shows a very high stability in aqueous solution (logK EuL = 25.7), a high relaxivity (8.5 mM -1 s -1 at 25 °C and 20 MHz) and a marked and selective relaxivity enhancement (37%) in the presence of Mg ...

Single-ion magnet behaviour in U(Tp(Me2))(2)I

Marinella Mazzanti

[U(TpMe2)2I] exhibits at low temperatures single molecule magnet (SMM) behaviour comparable to its bipyridine derivative and related single ion U(iii) complexes recently reported as SMMs. The trend of variation of the energy barrier for the magnetic relaxa ...

The first tetrameric cation-cation neptunyl(v) cluster, [NpO 2(salen) 4(μ 8-K) 2][K(18C6)Py] 2, has been synthesized in non-aqueous solution from the reaction of [(NpO 2Py 5)(KI 2Py 2)] n with K 2salen and its structure determined in the solid state and in ...

The reaction of the UO2+ precursor [(UO 2Py5)(KI2Py2)]n, with the potassium salt of the tetradentate aza β-diketiminate ligand L (L = 2-(4-tolyl)-1,3-bis(quinolyl)malondiiminate) affords the ...

Computing averages over a target probability density by statistical re-weighting of a set of samples with a different distribution is a strategy which is commonly adopted in fields as diverse as atomistic simulation and finance. Here we present a very gene ...
