Bis(4-amino-pyridinium) hexa-aqua-nickel(II) bis-(sulfate).

ABSTRACT: In the title compound, (C5H7N2)2[Ni(H2O)6](SO4)2, the Ni(II) cation is located on an inversion centre and is coordinated by six aqua ligands in a slightly distorted octa-hedral 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-amino-pyridinium cations are located between these layers and are connected to the anionic framework by N-H?O hydrogen bonds. Weak ?-? inter-actions between the pyridine rings, with a centroid-centroid distance of 3.754?(9)?Å, provide additional stability to the crystal packing.
