A new dimension in cyclic coinage metal pyrazolates: decoration with a second ring of coinage metals supported by inter-ring metallophilic interactions

Autor: Oliver S. Wenger, Franc Meyer, Kevin Pröpper, Sebastian Dechert, Michael John, Catherine Bronner, Ann Christin Jahnke, Jörg Teichgräber

Publikováno v: Journal of the American Chemical Society. 134(6)

When pyrazolate ligands with thioether chelate arms are used in cyclic coinage metal pyrazolates [Au(μ-pz)](n), the inner gold ring can be framed with an outer silver ring to give novel heterometallic double-crowned complexes [AuAg(μ-L(x))(BF(4))](

ChemInform Abstract: Luminescent Cyclometalated Gold(III) Complexes

Autor: Catherine Bronner, Oliver S. Wenger

Publikováno v: ChemInform. 43

Many luminescent gold(I) compounds are known, but in the vast majority of gold(III) complexes reported until recently, room temperature emission in fluid solution does not occur. As for other d8 and d6 metals, the key to obtaining gold(III) compounds

Kinetic Isotope Effects in Reductive Excited-State Quenching of Ru(2,2’-Bipyrazine)32+ by Phenols

Autor: Catherine Bronner, Oliver S. Wenger

Electron transfer (ET) from phenol molecules to a photoexcited ruthenium(II) complex was investigated as a function of the para-substituent (R = OCH3, CH3, H, Cl, Br, CN) attached to the phenols. For phenols with electron-donating substituents (R = O
