1,3:16,18‐Bis­(xylyl)‐30‐crown‐8

The title crown ether, C₂₈H₄₀O₈, crystallizes in an ortho­rhombic cell with the full mol­ecule generated from crystallographic inversion symmetry. The ring consists of 30 atoms which could potentially influence the size of the ring cavity and the conformational flexibility. Unusual C—O—C—C and O—C—C—O torsion‐angle geometries, deviating by as much as 30° from their ideal values, have been observed.
