The asymmetric unit of the title salt, C6H9ClN22+·2H2PO4, contains two dihydrogenphosphate anions and one 2-chloro­benzene-1,4-diaminium dication. The H2PO4 anions are inter­connected through strong O—H...O hydrogen bonds to form two-dimensional infinite layers parallel to (001). The organic entities are anchored to the inorganic layers through N—H...O hydrogen bonds, and through weak C—Cl...O halogen bonds [3.159 (2) Å, 140.48 (7)°]. No π–π stacking inter­actions between neighboring aromatic rings or C—H...π inter­actions towards them are observed. Minor disorder is observed for the Cl atom and one hy­droxy group [minor-component occupancy = 3.29 (9)%].

In the title compound, 2C8H12NO+·H2P2O72−, the linked PO4 groups of the diphosphate anion are almost eclipsed and the P—O—P angle is 134.45 (7)°. In the crystal, infinite ribbons of H2P2O72− anions propagate in [100], being linked by strong O—H...O hydrogen bonds. The 4-meth­oxy­benzyl­ammonium cations bond to the diphosphate chains by N—H...O and C—H...O links, and are themselves linked by C—H...π inter­actions.
