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.
