meso‐5,5,7,12,12,14‐Hexa­methyl‐4,11‐di­aza‐1,8‐diazo­nia­cyclo­tetra­decane (S)‐malate(2–) methanol disolvate: a chain of rings generated by two pairs of N—H⃛O hydrogen bonds

The title compound is a methanol‐solvated salt, C₁₆H₃₈N₄²⁺·C₄H₄O₅²⁻·2CH₃OH, in which the ionic components are linked into chains by two pairs of N—H⃛O hydrogen bonds H⃛O = 1.78–2.21 Å, N⃛O = 2.702 (14)–3.094 (8) Å and N—H⃛O = 160–179°]. The methanol mol­ecules are pendent from the chain and are linked to it by O—H⃛O hydrogen bonds H⃛O = 1.86 and 1.89 Å, O⃛O = 2.691 (9) and 2.708 (16) Å, and O—H⃛O = 168 and 165°].
