Ammonium and sodium salts (ion pairs) of a multi-interactive tri-(4-pyridyl) hexaazaphenalenyl anion (TPHAP(-)) showed completely different ion-conductive properties depending on the crystal structure. TPHAP columnar crystals showed a high conductivity of 10(-3) S cm(-1) while retaining their structures even under humid conditions, whereas TPHAP dimer crystals exhibited a conductivity of similar to 10(-5) S cm(-1) with crystallinity deterioration. The main unit structures induced by multi-interactivity realized different water accessibility, which explains the differences in their ion conductivity and stability against humidity.
