    • The mean interplanar separations between both the "inside" and "alongside" 1,5-dioxynaphthalene residues and the bipyridinium unit are in each case 3.5 Å. There are [C-H⋯O] hydrogen bonds (i) between one of the hydrogen atoms in the α-positions with respect to the nitrogen atoms on the bipyridinium units and a central polyether oxygen atom ([C⋯O], 3.38 Å; [H⋯O], 2.46 Å; [C-H⋯O], 161°) and (ii) between one of the methylene groups of the tetracationic cyclophane and the adjacent oxygen atom of the same polyether linkage ([C⋯O], 3.30 Å: [H⋯O], 2.45 Å; [C-H⋯O], 148°). Additionally, there are edge-to-face [C-H⋯π] interactions involving the hydrogen atoms in the 4- and 8-positions of the "inside" 1,5-dioxynaphthalene residues and the proximal p-phenylene rings of the tetracationic cyclophane (respectively: [H⋯π], 2.73 and 2.82 Å; [C-H⋯π], 145 and 141°).

    • The mean interplanar separations between both the "inside" and "alongside" 1,5-dioxynaphthalene residues and the bipyridinium unit are 3.33 and 3.35 Å. There are [C-H⋯O] hydrogen bonds (i) between diametrically opposite pairs of hydrogen atoms located in the α-positions with respect to the nitrogen atoms on the bipyridinium units and the oxygen atoms in the proximal polyether linkages (respectivley: [C⋯O]. 3.26, 3.30, and 3.23 Å; [H⋯O], 2.43, 2.44, and 2.45 Å; [C-H⋯O], 145, 148, and 138°) and (ii) between one of the methylene groups of the tetracationic cylophane and one of the oxygen atoms in one of the polyether linkages ([C⋯O], 3.12 Å; [H⋯O], 2.39 Å; [C-H⋯O], 133°). Additionally, there are two edge-to-face [C-H⋯π] interactions involving the "inside" 1,5-dioxynaphthalene residues and the proximal p-phenylene rings of the tetracationic cyclophane ([H⋯π], 2.72 and 2.76 Å; [C-H⋯π], 148 and 145°).
