Abstract

Structurally authenticated phosphonium salts yielded from the treatment of (phosphoniumn+)(Cl- or Br-)n and (imidazoliumn+)(X-)n, n = 1 or 2 have been examined using Hirshfeld surface analysis, revealing the domination of C-H⋯X non-classical hydrogen-bonding between the cations and anions. The crystalline salts of (phosphoniumn+)(X-)n (X- = [SCN]-, [N(CN)2]-, [C(CN) 3]-, [PF6]-, [CF3SO 3]- or [N(CF3SO2)2] -) were formed by metathetical exchange in the presence of p-sulfonatocalix[4]arene and aquated gadolinium ions.
