Abstract: The title compound, C5H14N22+·2H2AsO4-, contains a network of centrosymmetric doubly protonated 2-methylpiperazinium cations, showing disorder of the methyl group, accompanied by dihydogenarsenate anions. The component species interact by way of cation-to-anion N-HO and anion-to-anion O-HO hydrogen bonds, the latter leading to infinite sheets of the H2AsO4- anions containing R66(24) supramolecular loops.
