The title compound, (C5H7N2)2[Cu(H2O)6](SO4)2·4H2O [systematic name: bis(2-aminopyridinium) hexaaquacopper(II) bis(sulfate) tetrahydrate], comprises axially elongated hexaaqua-coordinated octahedral CuII ions located on an inversion centre, non-coordinating sulfate anions, 2-aminopyridinium cations and lattice water molecules. The crystal structure is built of successive inorganic and organic layers extending parallel to (001) that are connected by an extensive three-dimensional hydrogen-bonded network of the type O—H...O and N—H...O, as well as π–π interactions [centroid–centroid distance 3.4140 (14) Å, offset 0.277 Å].
