Abstract
The conformational behaviour of 25,27-dimethoxythiacalix[4]arene was studie d using NMR techniques and X-ray analysis. The title compound prefers a con e conformation in solution, while in the solid state it adopts a unique 1,2 -alternate conformation thus creating a novel type of molecular channel hel d together by pi-pi interactions.
