摘要：

A solid-state molecular rotator comprising [18]crown-6 was assembled into a crystalline array of (Cs+)(3)([18]crown-6)(3)(H+)(2) [PMo12O40](5-) whereby two Cs+([18]crown-6) supramolecular rotators were complexed with a two-electron-reduced alpha-[PMo12O40](5-) Keggin cluster. The size-compatible rotators of [18]crown-6 were directly complexed to an alpha-[PMo12O40](5-) axle through Cs+-O interactions. The investigation of the dynamics of the system revealed that two rotation frequencies for [18]crown-6 were observed by using temperature-dependent H-1 NMR studies, and these were dominated by intermolecular interactions in the solid state.
