摘要

A rotorlike supramolecular crystal, {[K(18-crown-6)]PbI₃}_∞, is composed of a linear [PbI₃]_∞ chain acting as a stator and [K(18-crown-6)]⁺ cations fastened to the [PbI₃]_∞ chain and K-I bond like rotators and axes, respectively. A reversible breaking-symmetry phase transition occurs at ∼305 K. Variable-temperature ¹H NMR spectra and dielectrics were used for the dynamic analysis of [K(18-crown-6)]⁺ cations in the crystal.
