In the crown ether ring of the title compound, C20H24O6· 2C6H3N3O7·3H2O, the O - C(H2) - C(H2) - O torsion angles indicate a gauche conformation of the ethyl-eneoxy units, while the C - O - C - C torsion angles indicate planarity of these segments; the dihedral angle between the two benzene rings is 44.53 (13)°. In both picric acid mol-ecules, one of the nitro groups is twisted away from the attached ring. The mol-ecules are linked into chains along the b axis via inter-molecular O - H⋯O hydrogen bonds. In addition, the crystal structure is stabilized by C - H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distance between benzene rings = 3.5697 (16) Å].
