✦ Synopsis

In the crystal structure of the title compound, 2C~5~H~6~N~5~
^+^·C~6~Cl~2~O~4~
^2−^·2H~2~O, two adeninium cations, one chloranilate dianion and two water molecules are held together by O—H...O, N—H...O, O—H...Cl and C—H...O hydrogen bonds, forming a centrosymmetric unit. The chloranilate dianion resides on an inversion centre. The anion and two cations are approximately coplanar, the dihedral angle between the planes of the adeninium cation and the chloranilate dianion being 3.25 (3)°. The crystal structure is stabilized by inter-unit N—H...N, N—H...O, N—H...Cl and O—H...N hydrogen bonds, forming a three-dimensional hydrogen-bonding network.
