The title molecular salts, C15H20NO+·C4H3O4−, (I), and C9H15INO+·C4H3O4−, (II), have very similar molecular geometries for both cation and anion. The anions of both (I) and (II) are practically planar (r.m.s. deviations = 0.062 and 0.072 Å, respectively) and adopt a rare symmetrical geometry with the hydroxy H atom approximately equidistant from the two O atoms. In their crystals, the cations and anions in both (I) and (II) form tight ionic pairsviastrong N—H...O hydrogen bonds, with a roughly perpendicular disposition of the anion to the furan ring of the cation. This ion-pair conformation appears to correlate with the lack of reactivity of these salts in [4 + 2] cycloaddition reactions. In the extended structures of (I) and (II), the ion pairs form hydrogen-bonded chains propagating along [010] and [001], respectively,viaN—H...O hydrogen bonds.

The [PW12O40]3−[M+(H2O)16]3 is a “hydrogen bonded” ion-pair complex for M = Li, Na and K, but is a “contact” ion-pair complex for M = Rb and Cs, intermolecular charge transfer from the solvated counter cations M+(H2O)16 to the anion [PW12O40]3−.
