Abstract

Supramolecular 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+(150-crown-5)2]2 was 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.
