Supramolecular assemblies of ammonium ions (NH4+) with crown ethers form a variety of NH4+(crown ether) supramolecular cation (SC+) structures within the range of [Ni(dmit)2] salts. A new pyramidal NH4+(12-crown-4) structure is found in the NH4+(12-crown-4)[Ni(dmit)2]3(CH3CN)2 salt. The SC+ structures in the NH4+(crown ether)[Ni(dmit)2] series vary from pyramidal-, sandwich-, to disk-shaped-structures with the crown ethers 12-crown-4, 15-crown-5, and 18-crown-6, respectively.
