description The mol­ecule of the title compound {systematic name: 17,35-bis­[(2-propyn-1-yl­oxy)meth­yl]-2,5,8,11,14,20,23,26,29,32-deca­oxatricyclo­[31.3.1.1(15,19)]octa­triaconta-1(37),15,17,19 (38),33,35-hex­a­­ene}, C(36)H(48)O(12), has crystallographic inversion symmetry and adopts a chair-like conformation. The polyether bridges of the macrocycle adopt gauche conformations and the cavity of the macrocycle is collapsed. In the crystal structure, there are weak inter­molecular C—H⋯O hydrogen bonds driven in part by the elevated acidity of acetylenyl H atoms.
