Secondary N-nitrosocarbamate anions: Structure and alkylation reactions. A DFT study
The current article reports theoretical studies (DFT: B3LYP/6-31CG(d)) on the structure and alkylation reactions of the anions of some secondary N-nitrosocarbamates, a class of ambident nucleophiles whose chemistry has been little explored. Several anions (1–4), with an increasin

In the course of work on the anion condensation of Cd and Zn halides, the crystal structures and 7 9 , 8 1 Br N Q R spectra of 2,2-dimethyl-l,3-propanediammonium tetrabromocadmate(II) monohydrate (1) and dimethylammonium tetrabromozincate(II) (2), and 7 9 8 1 Br N Q R spectra of
Cluster anions: Structure, interactions, and dynamics in the sub-nanoscale regime
This article reflects on several recent advances in the studies of structure and dynamics of cluster anions, both as unique species and as a conceptual bridge between isolated molecules and the condensed phase. Applications involving photofragment and photodetachment spectroscopy
Ionic liquids based on diethylmethyl(2-methoxyethyl)ammonium cations and bis(perfluoroalkanesulfonyl)amide anions: influence of anion structure on liquid properties.
A series of diethylmethyl(2-methoxyethyl)ammonium (DEME)-based ionic liquids were prepared using bis(perfluoroalkanesulfonyl)amide (C(n)F(2n+1)SO(2))(2)N anions with different perfluoroalkyl chain lengths (n = 0, 1, 2, 3, and 4), and the influence of the structural variation on t

The structure of the condensed bromocadmate anions in [C(NH2)3]Cd2Br5 (1) and [H2NNH3]3CdBr5 (2) were studied at room temperature by X-ray diffraction. (1) crystallizes with double-chains bridged by Br atoms (orthorhombic, Pmmn, Z = 2, a = 1394.0(5), b = 394.5(1), c = 1086.9(5) p
Planarized B-phenylborataanthracene anions: structural and electronic impacts of coplanar constraint.
Potassium and lithium salts of anionic B-phenylborataanthracenes, whose phenyl groups were fixed in a coplanar fashion, were synthesized. These compounds exhibited solvent-separated ion pair structures both in the crystalline state and in solution. Planarization of the phenyl moi
