Autor: Kurt F. Hoffmann, Anja Wiesner, Carsten Müller, Simon Steinhauer, Helmut Beckers, Muhammad Kazim, Cody Ross Pitts, Thomas Lectka, Sebastian Riedel
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-7 (2021)
Unlike other halogen atoms, the ability for fluorine to exist in a [C–X–C]+ connectivity pattern has only been shown in spectroscopic studies. Here the authors present a single crystal structure of a fluoronium cation, characterized by X-ray diff

Publikováno v: ChemistryOpen, Vol 10, Iss 2, Pp 255-264 (2021)
Abstract The ionic liquid (IL) trihalogen monoanions [N2221][X3]− and [N2221][XY2]− ([N2221]+=triethylmethylammonium, X=Cl, Br, I, Y=Cl, Br) were investigated electrochemically via temperature dependent conductance and cyclic voltammetry (CV) mea

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-6 (2018)
While transition metal complexes bearing terminal oxido ligands are common, those of group 11 elements have yet to be experimentally observed. Here, Riedel and colleagues synthesise molecular oxygen fluorides of copper, silver and gold, and show that

Matrix Isolation Spectroscopic and Relativistic Quantum Chemical Study of Molecular Platinum Fluorides PtF n ( n =1–6) Reveals Magnetic Bistability of PtF 4
Autor: Lin Li, Sebastian Riedel, Martin Kaupp, Robert Müller, Helmut Beckers, Gene Senges, Artur Wodyński
Publikováno v: Chemistry – A European Journal. 27:13642-13650
Molecular platinum fluorides PtFn , n=1-6, are prepared by two different routes, photo-initiated fluorine elimination from PtF6 embedded in solid noble-gas matrices, and the reaction of elemental fluorine with laser-ablated platinum atoms. IR spectra

Cleavage of the N≡N Triple Bond and Unpredicted Formation of the Cyclic 1,3‐Diaza‐2,4‐Diborete (FB) 2 N 2 from N 2 and Fluoroborylene BF
Autor: Haoyu Ye, Helmut Beckers, Xuefeng Wang, Bing Xu, Yan Lu, Sebastian Riedel, Juanjuan Cheng
Publikováno v: Angewandte Chemie International Edition. 60:17205-17210
A complete cleavage of the triple bond of N2 by fluoroborylene (:BF) was achieved in a low-temperature N2 matrix by the formation of the four-membered heterocycle FB(μ-N)2 BF, which lacks a trans-annular N-N bond. Additionally, the linear complex FB

Molecular oxofluorides OMFn of nickel, palladium and platinum: oxyl radicals with moderate ligand field inversion
Autor: Tilen Lindic, Lin Li, Dirk Andrae, Tony Stüker, Tobias Schlöder, Helmut Beckers, Sebastian Riedel
Publikováno v: Inorganic Chemistry Frontiers. 8:1215-1228
Terminal oxo compounds of high-valent late transition metals attracted attention because of their peculiar metal–oxygen bond in which the oxo ligand exhibits an electrophilic and distinct radical oxyl (O˙−) rather than the commonly expected nucl

Insights into the Topology and the Formation of a Genuine ppσ Bond: Experimental and Computed Electron Densities in Monoanionic Trichlorine [Cl3]−
Autor: Karsten Sonnenberg, Sebastian Riedel, Helena Keil, Dietmar Stalke, Carsten Müller, Helmut Beckers, Regine Herbst-Irmer
Publikováno v: Angewandte Chemie (International Ed. in English)
So far, several publications have discussed the bonding concepts in polyhalides on a theoretical basis. In particular, the trichlorine monoanion is of great interest because its structure should be symmetrical and show two equidistant Cl−Cl bonds.

Investigation of Molecular Iridium Fluorides IrF n ( n =1–6): A Combined Matrix‐Isolation and Quantum‐Chemical Study
Autor: Yan Lu, Yetsedaw A. Tsegaw, Artur Wodyński, Lin Li, Helmut Beckers, Martin Kaupp, Sebastian Riedel
Publikováno v: Chemistry – A European Journal. 28
The photo-initiated defluorination of iridium hexafluoride (IrF6) was investigated in neon and argon matrices at 6 K, and their photoproducts are characterized by IR and UV-vis spectroscopies as well as quantum-chemical calculations. The primary phot
