Tetra-aqua-(2,2'-bipyridine-κ²N,N')nickel(II) sulfate.
The asymmetric unit of the title complex, [Ni(C₁₀H₈N₂)(H₂O)₄]SO₄, consists of a complex [Ni(bipy)(H₂O)₄]²⁺ cation (bipy = 2,2'-bipyridine) and a non-coordinating [SO₄]²⁻ anion. The Ni(II) atom is six-coordinated in a distorted octa-hedral geometry defined by the two N atoms of the bipy ligand and four water O atoms. The crystal structure contains extensive classical O-H⋯O hydrogen bonds, which link the ions into a two-dimensional array in the ab plane. Layers are connected into a three-dimensional supra-molecular structure by C-H⋯O inter-actions.
