In the title salt hydrate, C(22)H(30)N(2)O(6)(2+)center dot 2Cl(-)center dot CH(4)O, the dication adopts a U-shaped conformation whereby the benzene rings are splayed out from the chain linking them. All components of the asymmetric unit are linked into a cohesive entity by a combination of O-H center dot center dot center dot Cl(-), N(+)-H center dot center dot center dot Cl(-) and N(+)-H center dot center dot center dot O charge-assisted hydrogen-bonding interactions. The assemblies thus formed are linked into supramolecular helical chains along [010] via C-H center dot center dot center dot O contacts. The resulting chains are, in turn, consolidated into the three-dimensional crystal structure by C-H center dot center dot center dot pi contacts.
