Abstract
In the title compound, (C5H7N2)2[Ni(H2O)6](SO4)2, the NiII cation is located on an inversion centre and is coordinated by six aqua ligands in a slightly distorted octahedral coordination environment. The [Ni(H2O)6]2+ ions are connected through an extensive network of O—H⋯O hydrogen bonds to sulfate anions, leading to the formation of layers parallel to (001). The 4-aminopyridinium cations are located between these layers and are connected to the anionic framework by N—H⋯O hydrogen bonds. Weak π–π interactions between the pyridine rings, with a centroid–centroid distance of 3.754 (9) Å, provide additional stability to the crystal packing.
