Anion–anion and anion–neutral triel bonds
TrCl4−(Tr = Al, Ga, In, Tl) anion is able to engage in complexes with two Lewis bases: neutral NH3or the CN−anion through a triel bond. Complexation leads to two types of geometries: axial and equatorial.

Anion⋅⋅⋅Anion Interactions Involving σ‐Holes of Perrhenate, Pertechnetate and Permanganate Anions [PDF]
AbstractIn this communication experimental and theoretical results are reported affording strong evidence that interactions between electron rich atoms and the metal of tetroxide anions of group 7 elements are a new case of attractive and σ‐hole interactions.

Design and Investigation of Superatoms for Redox Applications: First-Principles Studies
A superatom is a cluster of atoms that acts like a single atom. Two main groups of superatoms are superalkalis and superhalogens, which mimic the chemistry of alkali and halogen atoms, respectively.

Anion⋅⋅⋅Anion Coinage Bonds: The Case of Tetrachloridoaurate [PDF]
AbstractInteractions in crystalline tetrachloridoaurates of acetylcholine and dimethylpropiothetine are characterized by Au⋅⋅⋅Cl and Au⋅⋅⋅O short contacts. The former interactions assemble the AuCl4− units into supramolecular anionic polymers, while the latter interactions append the acetylcholine and propiothetine units to the polymer.

To be detectable in space via radio astronomy, molecules should have a permanent dipole moment. This is the plausible reason why HCnH chains are underproportionally represented in the interstellar medium in comparison with the isoelectronically ...

Using DFT/(B3LYP/wB97XD/B2PLYPD) and OVGF electronic structure methods with flexible atomic orbital basis sets, we examined the series of polynuclear superhalogen anions matching the (BF3(BN)nF4n+1)– formula (for n = 1-10,13,18-20) containing alternately

Development of ion chromatography methods for the determination of trace anions in ultra pure water from power plants [PDF]
A suppressed ion chromatography (IC) technique, using a carbonate/hydrogen carbonate or a hydroxide eluent, has been evaluated as a monitoring tool for the detection of major anions (F-, Cl-, NO3-, PO43- and SO42-) in ultra pure water and condensed steam
