The asymmetric unit of the title compound, C 44 H 64 O 4 ÁC 4 H 8 O, comprises two crystallographically independent calixarene molecules, which display a partial cone conformation, and two tetrahydrofuran molecules. The crystal packing is stabilized by C-HÁ Á Á contacts involving the methoxy groups,
