Insights into the microbial reduction of pentavalent and hexavalent uranium species by Shewanella oneidensis MR-1

Decades of uranium-related activities such as ore mining, nuclear power generation, weapon manufacture, storage of nuclear wastes, have contributed to the release of U in the environment. U occurrence is concerning, since in surface environments, U is typi ...

Assembly of High-Spin [Fe-3] Clusters by Ligand-Based Multielectron Reduction

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Davide Toniolo

The hexanuclear [Na12Fe6(tris-cyclo-salophen)(2)(THF)(14)], 1-THF, and the trinuclear [Na6Fe3(tris-cyclo-salophen)(py)(9)], 1-py, Fe(II) clusters can be easily assembled in one step from the ligand-based reduction of the [FeII(salophen)(THF)] complex. Thes ...

Activation of small molecules promoted by multimetallic complexes supported by redox active ligands

Davide Toniolo

The activation of small molecule is a topic of high current interest. A variety of homogeneous end heterogeneous catalysts have been studied to be able to promote chemical transformation of industrial relevance under mild condition and therefore decrease t ...

Stability of metallo-porphyrin networks under oxygen reduction and evolution conditions in alkaline media

Klaus Kern, Jan Gui-Hyon Dreiser, Markus Etzkorn, Claudius Morchutt, Sebastian Stepanow, Benjamin Wurster

Transition metal atoms stabilised by organic ligands or as oxides exhibit promising catalytic activity for the electrocatalytic reduction and evolution of oxygen. Built-up from earth-abundant elements, they offer affordable alternatives to precious-metal b ...

Deciphering crystal packing effects in the spin crossover of six [Fe-II(2-pic)(3)]Cl-2 solvatomorphs

Sergio Vela Llausi

In this work we investigate how the crystal packing affects the spin crossover (SCO) of [Fe-II(2-pic)(3)]Cl-2. Four alcohol solvatomorphs of this compound have been reported to present a transition from a singlet low spin (LS, S = 0) to a quintet high spin ...

Effects of Zeolite Structural Confinement on Adsorption Thermodynamics and Reaction Kinetics for Monomolecular Cracking and Dehydrogenation of n-Butane

Berend Smit

The effects of zeolite structure on the kinetics of n-butane monomolecular cracking and dehydrogenation are investigated for eight zeolites differing in the topology of channels and cages. Monte Carlo simulations are used to calculate enthalpy and entropy ...

Long-Range Bonding/Nonbonding Interactions: A Donor Acceptor Resonance Studied by Dynamic NMR

Long-range bonding interactions were evaluated using variable-temperature NMR spectroscopy and suitable 2'-CH2X-substituted phenylpyridines (X = Me, NMe2, OMe, F). It was found that the arylpyridyl rotational barriers were lower when electronegative atoms ...

Triphenyltin(IV) adducts of diphosphoryl ligands: structural, electronic and energy aspects from X-ray crystallography and theoretical calculations

Kurt Schenk

Some triphenyltin(IV) adducts with a family of diphosphoryl ligands, RR'P(O)-X-P(O)RR' (R = OPh, Ph, R' = R, An (aniline)) and X = 1,4-OC6H4O, 1,4-OC6H4NH, 1,4-NHC6H4NH 1,4-(NHCH2)(2)C6H4, 1,3-(NHCH2)(2)C6H4 and piperazine have been synthesized and charact ...

Structure of Zirconocene Complexes Relevant for Olefin Catalysis: Infrared Fingerprint of the Zr(C5H5)(2)(OH)(CH3CN)(+) Cation in the Gas Phase

Ulrich Lorenz

Cationic zirconocene complexes are active species in Ziegler-Natta catalysis for olefin polymerization. structure and metal-ligand bond strength strongly influence their activity. In the present work, the multiphoton dissociation (IRMPD) spectrum of mass s ...

Novel Ruthenium Complexes with Sterically Demanding Cyclopentadienyl Ligands

Barnali Dutta

Investigations of ruthenium halfsandwich complexes have mostly focused on Cp and Cp* based derivatives due to the availability of easily accessible starting materials. However, it is interesting to have complexes with substituted cyclopentadienyl ligands i ...
