C−C Bond Cleavage and Carbonylation Enabled by an NNN-Pincer Uranium Scaffold via Metal-Arene Interaction

Yue Pang, Rosario Scopelliti, Marinella Mazzanti

Raw data accompanying the paper. Metal-arene complexes have recently attracted an increasing interest in f-element chemistry, but the functionalization of arenes mediated by uranium-arene interactions is limited to a single example. Here, we report a new ...

Structure and small molecule activation reactivity of a metallasilsesquioxane of divalent ytterbium

Anna Maria Dabrowska, Rosario Scopelliti, Marinella Mazzanti, Aurélien René Willauer

The first metallasilsesquioxane of a divalent lanthanide, Yb{Cy7Si7O11(OSiMe3)}(THF),1, was synthesized and structurally characterized. The Cy7Si7O11(OSiMe3)(2-)ligands in1bind two Yb(ii) ions in a bridging mode. The dinuclear complex effects the two- ...

Bonding and Reactivity in Terminal versus Bridging Arenide Complexes of Thorium Acting as Th II Synthons

Marinella Mazzanti

Thorium redox chemistry is extremely scarce due to the high stability of ThIV. Here we report two unique examples of thorium arenide complexes prepared by reduction of a ThIV-siloxide complex in presence of naphthalene, the mononuclear arenide complex [K(O ...

The isotopic signature of U(V) during bacterial reduction

Marinella Mazzanti, Rizlan Bernier-Latmani, Radmila Faizova, Ashley Richards Brown, Margaux Camille Andréa Molinas

The two-step electron transfer during bacterial reduction of UVI to UIV is typically accompanied by mass-independent fractionation of the 238U and 235U isotopes, whereby the heavy isotope accumulates in the reduced product. However, the role of the UV inte ...

Synthesis and Structure of Nitride-Bridged Uranium(III) Complexes

Rosario Scopelliti, Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The reduction of the nitride-bridged diuranium(IV) complex Cs[{U(OSi((OBu)-Bu-t)(3))(3)}(2)(mu-N)] affords the first example of a uranium nitride complex containing uranium in the +III oxidation state. Two nitride-bridged complexes containing the heteromet ...

Dinitrogen Reduction and Functionalization by a Siloxide Supported Thulium-Potassium Complex for the Formation of Ammonia or Hydrazine Derivatives

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

The dinitrogen (N2) chemistry of lanthanides remains less developed compared to the d-block metals and lanthanide-promoted N2 functionalization chemistry in well-defined lanthanide complexes remains elusive. Here we report the synthesis and characterizatio ...

A versatile route to homo- and hetero-bimetallic 5f–5f and 3d–5f complexes supported by a redox active ligand framework

Marinella Mazzanti, Julie Renée Michelle Andrez, Davide Toniolo

The salt-elimination reaction of the complex [Na2U(bis-salophen)] with metal halides provides an entry to the synthesis of well-defined homobimetallic uranium–uranium and rare heterobimetallic uranium–cobalt and uranium–nickel complexes supported by a redo ...

Confinement of a tris-aqua Gd(III) complex in silica nanoparticles leads to high stability and high relaxivity and supresses anion binding

Marinella Mazzanti

The water soluble tris-aqua complex Gd(dhqN-SO3)(H2O)(3) based on a hexadentate hydroxyquinoline ligand shows high thermodynamic stability and high relaxivity (12.54 mM(-1) s(-1) at 1.2 T). Its non-covalent confinement in 25 nm silica nanoparticles p ...

A tetranuclear samarium(II) inverse sandwich from direct reduction of toluene by a samarium(II) siloxide

Marinella Mazzanti, Farzaneh Fadaei Tirani, Davide Toniolo, Rory Patrick Kelly

The dinuclear SmII complex, [Sm2L4(dme)] (L = OSi(OtBu)3), is easily obtained from the protonolysis reaction of [Sm{N(SiMe3)2}(thf)2] with HOSi(OtBu)3. This complex reacts slowly with toluene, resulting in the isolation of the triple-decker arene-bridged S ...

A zig-zag uranyl(V)- Mn(II) single chain magnet with a high relaxation barrier

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The synthesis, structural characterization and magnetic properties of a 1D zig-zag coordination polymer based on a cation-cation [((UO2)-O-V)Mn-II] repeated unit are reported; it shows single chain magnet (SCM) behaviour with a high energy barrier of 122 K ...

Surface enhanced nuclear magnetic resonance spectroscopy at solid-liquid interfaces using Overhauser dynamic nuclear polarization

David Lyndon Emsley, Marinella Mazzanti, Yu Rao, Marcel Levien, Pragati Pandey

While solid-liquid interfaces are ubiquitous, detecting the associated surface sites under ambient conditions remains a grand challenge. Previously, we demonstrated the hyperpolarization by Overhauser effect dynamic nuclear polarization (OE-DNP) of ligands ...

Ferrocene-Based Tetradentate Schiff Bases as Supporting Ligands in Uranium Chemistry

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

Uranyl(VI), uranyl(V), and uranium(IV) complexes supported by ferrocene-based tetradentate Schiff-base ligands were synthesized, and their solid-state and solution structures were determined. The redox properties of all complexes were investigated by cycli ...

Toward the Rational Design of Lanthanide Coordination Polymers: a New Topological Approach

Jean-Claude Bünzli, Marinella Mazzanti

The implementation of four bidentate building blocks into a highdenticity linker with a flexible spacer leads to a predisposed ligand that allows one to direct the self- assembly of 1D functional coordination polymers. This is illustrated by the assembly u ...
