The title 22-crown-6 unit, C(26)H(28)O(6), comprising of three benzo groups and triethyl­ene glycol, was prepared by the reaction of α,α′-dibromo-p-xylene with 1,8-bis­(2-hydroxy­phen­oxy)-3,6-dioxaoctane in the presence of Cs(2)CO(3) with tetra­hydro­furan (THF) and recrystallized from dichloro­methane–hexane (1:20 v/v) at room temperature. In the mol­ecular structure, two O atoms of the central ethyl­ene glycol in the triethyl­ene glycol unit exhibit exo conformations due to intra­molecular C—H⋯O inter­actions. A number of C—H⋯O and C—H⋯π inter­molecular inter­actions contribute to the stabilization of the crystal packing.
