Abstrakt: AbstractSupramolecular cations (SC+) of K+, Rb+, or NH4+(crown ether) were incorporated into the monovalent [Ni(dmit)2]−salts. The K+and Rb+(DA18-crown-6) units had a planar disk-shaped SC+structure, while the [NH4+(15-crown-5)2]2was the barrel type SC+structure. The [Ni(dmit)2]−arrangement and magnetic properties of these salts depended on the coordination properties in the cation structures.
