## Abstract The stereochemistry in solution of three octathia[2.2.2.2]metacyclophanes has been investigated by means of ^1^H NMR spectroscopy. The results lead to the conclusion that the saddle or crown conformation is preferred for these compounds, depending on the substitution pattern of the cons
