17-formyl-2,5,8,11,14-penta-oxabicyclo-[13.4.0]nona-deca-15,17,19-triene), C(15)H(20)O(6), the 15-crown-5 ring adopts a twisted conformation. The formyl group is coplanar with the benzene ring. The crystal packing is stabilized by C-H⋯O inter-actions involving the C=O group and ether O atoms as acceptors and methyl-ene CH groups as donors.
