In the crystal structure of the title compound, C(4)H(10)NO(+)·C(6)HCl(2)O(4) (-)·CH(4)O, the components are held together by bifurcated O-H⋯(O,O), O-H⋯(O,Cl) and N-H⋯(O,O) hydrogen bonds into a centrosymmetric 2+2+2 aggregate. The aggregates are further connected by another bifurcated N-H⋯(O, O) hydrogen bond, forming a double-tape structure along the b axis. A weak C-H⋯O inter-action is observed between the tapes.
