Anion Resonances and Photoelectron Spectroscopy of the Tetracenyl Anion

The Journal of Physical Chemistry A, 2021
The photoelectron spectroscopy of the tetracenyl anion using slow electron velocity-map imaging (SEVI) of cryogenically cooled ions is presented. The total photodetachment yield as a function of photon energy is used to reveal a rich manifold of anion excited states above the detachment threshold.

Radical Anions, Radical‐Anion Salts, and Anionic Complexes of 2,1,3‐Benzochalcogenadiazoles

Chemistry – A European Journal, 2018
AbstractBy means of cyclic voltammetry (CV) and DFT calculations, it was found that the electron‐acceptor ability of 2,1,3‐benzochalcogenadiazoles 1–3 (chalcogen: S, Se, and Te, respectively) increases with increasing atomic number of the chalcogen. This trend is nontrivial, since it contradicts the electronegativity and atomic electron affinity of the

The Trifluoromethyl Anion

Angewandte Chemie, 2015
AbstractFirst evidence for the existence of free trifluoromethyl anion CF3− has been obtained. The 3D‐caged potassium cation in [K(crypt‐222)]+ is inaccessible to CF3−, thus rendering it uncoordinated (“naked”). Ionic [K(crypt‐222)]+ CF3− has been characterized by single‐crystal X‐ray diffraction, solution NMR spectroscopy, DFT calculations, and ...

Anionic Iminoborane as Boryl Anion Synthon

Angewandte Chemie
Abstract Classical iminoboranes, extensively investigated since the 1980s, are defined by 1,2‐dipolar reactivity in which the boron center remains exclusively electrophilic. Here, we report an anionic iminoborane, [Ar─B≡N─Flu] − , in which substitution at nitrogen with a ...

Geometrically diverse anions in anion–π interactions

Supramolecular Chemistry, 2011
The role of different anion geometries in anion–π interactions is discussed. The chemistry described herein is different to the interaction of spherical cations with aromatics. The influence of different geometries makes selective anion recognition more complicated than respective cation sensing.

Anion−Anion Assembly in Crystal of Sodium Nitroprusside

The Journal of Physical Chemistry A, 2008
The experimental charge density in the crystal of disodium pentacyanonitrosoferrate (sodium nitroprusside) dihydrate was analyzed in detail by means of Bader's atoms in molecules theory. It was shown that nitroprusside anion is involved in relatively strong self-interactions through the nitroso group.

Anion‐Anion Complexes Established between Aspartate Dimers

ChemPhysChem, 2020
AbstractStable dimers aspartate‐aspartate have been studied in aqueous and gas phase through theoretical simulations. The polarizable continuum model (PCM) has been applied to simulate the effect of the hydration on monomers and complexes. The quantum theory of atoms in molecules (QTAIM) and the interacting quantum atoms (IQA) scheme has been used to ...

Molecular Anions

The Journal of Physical Chemistry A, 2008
The experimental and theoretical study of molecular anions has undergone explosive growth over the past 40 years. Advances in techniques used to generate anions in appreciable numbers as well as new ion-storage, ion-optics, and laser spectroscopic tools have been key on the experimental front.

Outer-sphere Anion-Anion Complexes

Mendeleev Communications, 1995
Bands resulting from contact outer-sphere anion-anion interactions, have been found in the electronic absorption spectra of systems containing simultaneously the anions [FeNO(CN) 5 ] 2– or [Co edta] – and nucleophilic anions ( I − , SC N − and S 2 O 3 2 − ) ; the fraction of complex anions occurring in the contact
