Abstract

The title compound, C20H26O4, crystallizes such that the alkyl chain adopts an all-anti conformation. The crystal packing displays edge-to-face arene–arene inter­actions with a dihedral angle of 87°. The complete molecule is generated by inversion symmetry.

Highlights

  • The title compound, C20H26O4, crystallizes such that the alkyl chain adopts an all-anti conformation

  • The complete molecule is generated by inversion symmetry

  • The rather large crystal used for data collection was chosen in order to optimize data intensity
