M(super +)(12-crown-4) supramolecular cations (M(super +) = Na+, K+, Rb+, and NH(super 4+) within Ni(2-thioxo-1, 3-dithiole-4,5-dithiolate)(sub 2) molecular conductor

Monovalent cations (M(super +) = Li(super +), Na(super +), K(super +). Rb(super +), and NH(sub 4)(super +) and 12-crown-4 were assembled to new supramolecular cation (SC(super +)) structures of M(super +)(12-crown-4)(sub n) (n - 1 and 2). The SC(super +) structures were incorporated into the electrically conducting Ni-(dmit)(sub 2) salts.
