It was shown that N2F4 and BF3 do not form a stable adduct at temperatures as low as -78°C. The vibrational and 19F NMR spectra of the N2F3+ cation were reexamined. All the experimental data are consistent with a planar structure of symmetry Cs for N2F3+. The previously reported ...

A theoretical investigation of the alteration with salt concentration of both isoelectric (isoionic) reaction and the shape and direction of the ionisation curves is made, with regard to ampholytes capable only of combining with hydrogen ions, on the basis of the Debye-Hückel formulæ and ...

As mentioned before, the [Ni(dmit)2] molecules do not necessarily form stacking structures in the monovalent salts. Thus, a large structural diversity in [Ni(dmit)2] arrangements in these crystals is expected. The assemblies of 1/2 spins (one unpaired electron on every [Ni(dmit)2]) in ...
This work shows for the first time clear structural evidence for the switch between the delocalized, aromatic form and the localized, diene‐like isomer of a heterole anion triggered by the coordination of an alkali metal cation. More information can be found in the Full Paper by T. Müller ...
(1) the unstability of chloriranium ion makes it more likely to form a free carbocation, resulting in low stereoselectivity or decomposition; (2) the chlorenium ion is more reactive so that it tends to react with nucleophiles before forming a chloriranium ion (Fig.3a). Therefore, developing ...
