Supramolecular Rotor: Adamantylammonium([18]crown-6) in [Ni(dmit)2]- Salt

Abstract

Adamantylammonium (ADNH3+) was complexed with [18]crown-6, forming a supramolecular cation of (ADNH3+)([18]crown6), which was introduced into a [Ni(dmit)2]- salt as a supramolecular rotor. The cation layers were alternately arranged with [Ni(dmit)2]- layers in the crystal, in which the molecular rotation of (ADNH3+)([18]crown-6) was confirmed from the temperature-dependent solid-state 1H NMR.
