Abstract

A solid-state molecular rotator comprising [18]crown-6 was assembled into a crystalline array of (Cs+)3([18]crown-6) 3(H1)2[PMo12O40] 5, whereby two Cs1([18]crown-6) supramolecular rotators were complexed with a two-electron-reduced α-[PMo12O 40]5 Keggin cluster. The size-compatible rotators of [18]crown-6 were directly complexed to an α-[PMo12O 40]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 1H NMR studies, and these were dominated by intermolecular interactions in the solid state.
