A hydrogen-bonded adduct containing seven-component supramolecular aggregates

The title compound is a salt, 3,6,9,16,19,22-hexaaza­tri­cyclo­[22.2.2.2^11,14]­triaconta-1(26),11(29),12,14(30),24,27-hexa­ene–3,5-di­nitro­benzoic acid–methanol (1/4/2), C₂₄H₄₂N₆⁴⁺·4C₇H₃N₂O₆⁻·2CH₄O, in which the cation lies across a centre of inversion and one of the two independent anions is positionally disordered over two sets of atom sites having equal occupancy. The components are linked by four types of N—H⃛O hydrogen bond [N⃛O 2.674 (2)–2.815 (2) Å; N—H⃛O 149–163°] and one type of O—H⃛O hydrogen bond in which the acceptor is disordered over two closely adjacent sites [O⃛O 2.67 (4) and 2.75 (4) Å; O—H⃛O 172 and 173°], forming centrosymmetric seven-component aggregates.
