Cations and Anion - Europe PMC

Anion-cation interactions in a series of salts with substituted Hphen, Hbpy and H₂bpy cations and [W(CN)₈]^4- anion: polymer with "super-short" N-H⋯N hydrogen bridges containing exclusively anions and H.

The ten ion-pairs of [W 8] 4- with substituted Hphen and H n bpy n + were isolated, and the spectroscopic properties of these salts are investigated. n + cation are three salts with dimethyl-substituted H n bpy n + cation were structurally characterized. One of the anion's cyanido ligands, which is in the CNH form, is found in the salt's structure with H2 bpy. [W 8] 4- ] This situation is very unique, as well as the emergence of two water double bridges by water molecules in [W 8 ] 4-.
