An Iron Carbonyl Pyridonate Complex Related to the Active Site of the [Fe]-Hydrogenase (Hmd)

Rosario Scopelliti, Xile Hu, Blaise Valentin Obrist, Dafa Chen

A mononuclear iron bis(carbonyl) pyridonate complex (1), which exhibits several common structural features with the active site of the iron−sulfur cluster-free [Fe]- hydrogenase, was synthesized and characterized. Spectroscopic data of 1 suggests a 2+ oxid ...

Acetonitrile exchange kinetics on di- and trivalent lanthanide ions

Gabriella Eva Bodizs

The knowledge and understanding of the mechanism as well as the rate constant of the solvent exchange reactions are fundamental, since these reactions represent an important step in complex formation reactions on metal ions. Solvent exchange reactions in a ...

Metals in Proteins: Correlation Between the Metal-Ion Type, Coordination Number and the Amino-Acid Residues Involved in the Coordination

Ivan Dokmanic

Metal ions are constituents of many metalloproteins, in which they have either catalytic (metalloenzymes) or structural functions. In this work, the characteristics of various metals were studied (Cu, Zn, Mg, Mn, Fe, Co, Ni, Cd and Ca in proteins with know ...

Tuning the self-assembly of lanthanide triple stranded heterobimetallic helicates by ligand design

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

The heterobitopic ligands LAB4 and LAB5 have been designed and synthesised with the ultimate aim of self-assembling dual-function lanthanide complexes containing either a magnetic and a luminescent probe or two luminescent probes emitting at different wave ...

Structural and Luminescent Properties of Micro- and Nanosized Particles of Lanthanide Terephthalate Coordination Polymers

Jean-Claude Bünzli, Frédéric Gumy

Reaction in water between rare earth ions (Ln ) Y, La-Tm, except Pm) and the sodium salt of terephthalic acid leads to a family of lanthanide-based coordination polymers of general formula [Ln2(C8H4O4)3(H2O)4]n with Ln ) La-Tm or Y. The isostructurality of ...

Near-Infrared Luminescence of Nine-Coordinate Neodymium Complexes with Benzimidazole-Substituted 8-Hydroxyquinolines

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

A new class of benzimidazole-substituted 8-hydroxyquinoline ligands has been prepared that contain a monoanionic tridentate N,N,O-coordinating unit. These ligands form charge-neutral lanthanide complexes of the type [Ln(LR) 3] · nH2O or [Ln2(L2)3] · nH2O ( ...

Luminescent lanthanides bioprobes emitting in the visible and/or near-infrared ranges

Steve Comby

This Ph.D. work deals with the development of lanthanide-based bioprobes for biomedical analyses and imaging. For this purpose, two different approaches have been followed, one focusing on visible-emitting complexes, while the second addresses the sensitiz ...

Role of Inner- and Outer-Sphere Bonding in the Sensitization of EuIII-Luminescence Deciphered by Combined Analysis of Experimental Electron Density Distribution Function and Photophysical Data

Jean-Claude Bünzli

A series of lanthanide adducts with different amounts of 1,10-phenanthroline, chloride ions, and water molecules in the inner and outer coordination spheres are investigated with the aim of relating the chemical bonding pattern in the crystals to the lumin ...
