Benign synthesis of the unsymmetrical ligand N-(quinolin-8-yl) pyrazine-2-carboxamide. Preparation, electrochemistry, antibacterial activity, and crystal structures of Cu(II) and Zn(II) complexes

Hqpzc has been synthesized by a highly efficient procedure using the ionic liquid TBAB as an environmentally benign reaction medium. [Cu(qpzc)(OAc)]H2O (1) and [Zn(qpzc)(OAc)(H2O)] (2), complexes of the deprotonated ligand, qpzc [qpzc ...

Diamine Bis(phenolate) as Supporting Ligands in Organoactinide(IV) Chemistry. Synthesis, Structural Characterization, and Reactivity of Stable Dialkyl Derivatives

Marinella Mazzanti

The homoleptic compounds [U(salan-R2)2] (R = Me (1), tBu (2)) were prepared in high yield by salt-metathesis reactions between UI4(L)2 (L = Et2O, PhCN) and 2 equiv of [K2(salan-R2)] in THF. In contrast, the reaction of the tetradentate ligands salan-R2 wit ...

High-Resolution Scanning Tunneling Microscopy Characterization of Mixed Monolayer Protected Gold Nanoparticles

Francesco Stellacci, Paulo Henrique Jacob Silva, Quy Ong Khac, Javier Reguera Gomez, Kellen Michael Harkness, Mauro Moglianetti, Christoph Renner

Gold nanoparticles protected by a binary mixture of thiolate molecules have a ligand shell that can spontaneously separate into nanoscale domains. Complex morphologies arise in such ligand shells, including striped, patchy, and Janus domains. Characterizat ...

Synthesis, Characterization, and Reactivity of the First Osmium beta-Diketiminato Complexes and Application in Catalysis

Paul Joseph Dyson, Rosario Scopelliti, Andrew Douglas Phillips, Dominique Schreiber

The strongly chelating anionic beta-diketiminate ligand has been employed to formulate complexes involving almost every metal of the periodic table; however, the heavier metals of the d block remain relatively unexplored. This paper describes the synthesis ...

Low-temperature spin dynamics of a valence bond glass in Ba

Henrik Moodysson Rønnow, Julian Piatek

We carried out ac magnetic susceptibility measurements and muon spin relaxation spectroscopy on the cubic double perovskite Ba2YMoO 6, down to 50 mK. Below ∼1 K the muon relaxation is typical of a magnetic insulator with a spin-liquid type ground state, i. ...

Position-Dependent Extension of π-Conjugation in D-π-A Dye Sensitizers and the Impact on the Charge-Transfer Properties

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jinhyun Kim, Thomas Wesley Holcombe, Mateusz Barnaba Wielopolski, Yuxiang Yu

A series of five organic donor-π-bridge-acceptor (D-π-A) sensitizers is investigated within the context of their photoinduced charge-transfer properties. Thereby, the focus is set on the impact of structural modifications of the molecular architecture on t ...

Ruthenium(II)-Catalyzed Hydrogen Generation from Formic Acid using Cationic, Ammoniomethyl-Substituted Triarylphosphine Ligands

Paul Joseph Dyson, Gabor Laurenczy, Weijia Gan, Dennis Snelders

The selective catalytic decomposition of formic acid into hydrogen and carbon dioxide has been achieved in water under mild conditions. For the first time, a ruthenium ion in combination with series of oligocationic, ammoniomethyl-substituted triarylphosph ...

In Vivo 1H MRS at 14.1T for the Accurate Characterization of the Lipid Profile of the Mouse Liver

Rolf Gruetter, Hongxia Lei, Ana Francisca Leal Silva Soares

1H MRS was employed at 14.1T to non-invasively quantify the lipid content of small samples (8-15 µl). In the mouse liver, good spectral stability was achieved by running individual scans within one breathing cycle. Ultra short TE STEAM with water suppressi ...

Combined large spin splitting and one-dimensional confinement in surface alloys

Klaus Kern, Marco Grioni, Alberto Crepaldi

We have found and characterized, by angle-resolved photoelectron spectroscopy (ARPES), quasi-one-dimensional spin-split states in chain-like surface alloys formed by large Z elements (Bi and Pb) at the Cu(110) surface. The ARPES results are supported by fi ...

Subcomponent Self-Assembly of Rare-Earth Single-Molecule Magnets

A family of lanthanide complexes has been synthesized by the subcomponent self-assembly methodology. Molecular architectures, which were stable in solution and under ambient conditions, were designed by the in situ formation of ligands around lanthanide io ...
