Synthesis, structural determination, theoretical studies and catalytic activity of Mn(II) complex of N-isonicotinyl phosphoric triamide ligand
Kurt Schenk, Farzaneh Fadaei Tirani
synthesized and characterized by H-1, C-13, P-31 NMR and IR spectroscopies. The reaction of MnCl2 center dot 4H(2)O with L led to the formation of a new 3D system {MnL2Cl2}(n)center dot 34CH(3)OH (C-1). X-ray crystallographic data revealed that the ligand ...
Elsevier Science Sa2015Origin of Perpendicular Magnetic Anisotropy and Large Orbital Moment in Fe Atoms on MgO
Harald Brune, Stefano Rusponi, Marina Pivetta, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Luca Gragnaniello, Giulia Elisabetta Pacchioni
We report on the magnetic properties of individual Fe atoms deposited on MgO(100) thin films probed by x-ray magnetic circular dichroism and scanning tunneling spectroscopy. We show that the Fe atoms have strong perpendicular magnetic anisotropy with a zer ...
American Physical Society2015Anionic Bipyridyl Ligands for Applications in Metallasupramolecular Chemistry
Rosario Scopelliti, Kay Severin, Mathieu Jérémie Marmier, Clément Schouwey, Mirela Pascu
The facile synthesis of anionic bipyridyl ligands with dinuclear clathrochelate cores is described. These metalloligands can be obtained in high yields by the reactions of M(ClO4)(2)(H2O)(6) (M: Zn, Mn, or Co) with 4-pyridylboronic acid and 2,6-diformyl-4- ...
Wiley-Blackwell2014Electronic Elements Governing the Binding of Small Molecules to a [Fe]-hydrogenase Mimic
[Fe]-hydrogenase, one of three types of hydrogenases, activates molecular hydrogen. Here, using DFT computations, we examine the electronic elements governing the binding of small ligands to a recently synthesized [Fe]-hydrogenase biomimic. Computed reacti ...
Wiley-Blackwell2013Benign 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 ...
Taylor & Francis Ltd2013Mn2+ Complexes with 12-Membered Pyridine Based Macrocycles Bearing Carboxylate or Phosphonate Pendant Arm: Crystallographic, Thermodynamic, Kinetic, Redox, and 1H/17O Relaxation Studies
Mn2+ complexes represent an alternative to Gd3+ chelates which are widely used contrast agents in magnetic resonance imaging. In this perspective, the authors studied the Mn2+ complexes of two 12-membered, pyridine-contg. macrocyclic ligands bearing one pe ...
2011Novel Ruthenium Complexes with Sterically Demanding Cyclopentadienyl Ligands
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 ...
EPFL2010Structural determination of photochemically active diplatinum molecule by time-resolved EXAFS spectroscopy
Majed Chergui, Van Thai Pham, Amal El Nahhas, Renske Marjan van der Veen, Frederico Alves Lima
Metallica: A large contraction of the PtPt bond in the triplet excited state of the photoreactive [Pt2(P2O5H2)4]4- ion is determined by time-resolved X-ray absorption spectroscopy (see picture). The strengthening of the PtPt interaction is accompanied by a ...
2009Designing Simple Tridentate Ligands for Highly Luminescent Europium Complexes
Rosario Scopelliti, Jean-Claude Bünzli, Svetlana Eliseeva
A series of tridentate benz- ACHTUNGTRENUNGimidazole-substituted pyridine-2-carboxylic acids have been prepared with a halogen, methyl or alkoxy group in the 6-position of the benzimidazole ring, which additionally contains a solubilising N-alkyl chain. Th ...
2009Modulating the Near-Infrared Luminescence of Neodymium and Ytterbium Complexes with Tridentate Ligands Based on Benzoxazole-Substituted 8-Hydroxyquinolines
Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy
An improved synthesis of 2-(2′-benzothiazole)- and 2-(2′-benzoxazole)-8-hydroxyquinoline ligands that combine a tridentate N,N,O-chelating unit for metal binding and extended chromophore for light harvesting is developed. The 2-(2′-benzoxazole)-8-hydroxyqu ...
