Side‐On Bonded Beryllium Dinitrogen Complexes [PDF]
Angewandte Chemie International Edition, 2020 AbstractThe preparation and spectroscopic identification of the complexes NNBe(η2‐N2) and (NN)2Be(η2‐N2) and the energetically higher lying isomers Be(NN)2and Be(NN)3are reported. NNBe(η2‐N2) and (NN)2Be(η2‐N2) are the first examples of covalently side‐on bonded N2adducts of a main‐group element.

Bonding situations in tricoordinated beryllium phenyl complexes
Journal of Computational Chemistry, 2022 AbstractThe bonding situation in the tricoordinated beryllium phenyl complexes [BePh3]−, [(pyridine)BePh2] and [(trimethylsilyl‐N‐heterocyclic imine)BePh2] is investigated experimentally and computationally. Comparison of the NMR spectroscopic properties of these complexes and of their structural parameters, which were determined by single crystal X ...

Anomalous two-photon Compton scattering
New Journal of Physics, 2021 X-ray free-electron lasers can generate radiation pulses with extreme peak intensities at short wavelengths. This enables the investigation of laser–matter interactions in a regime of high fields, yet at a non-relativistic ponderomotive potential, where ...

Insights into Molecular Beryllium–Silicon Bonds [PDF]
Inorganics, 2017 We present the synthesis of two silyl beryllium halides HypSiBeX∙(thf) (HypSi = Si(SiMe3)3, X = Cl 2a, I 4a) and the molecular structure of 2a as determined by single crystal X-ray diffraction. Compounds 2a and 4a were characterized via multi-nuclear NMR spectroscopy (1H, 9Be, 13C, 29Si), and the bonding situation was further investigated using quantum
