Abstract: In the title compound, [Ni(C₁₀H₈N₂)(H₂O)₄](C₈H₁₀O₄), the Ni^II ion is located on a twofold rotation axis and has a distorted octahedral geometry formed by a chelating 2,2'-bipyridine ligand and four water molecules. The disordered cyclohexane-1,4-dicarboxylate dianion is located across another twofold rotation axis and adopts a boat conformation. O-HO hydrogen bonding between the complex cation and the cyclohexane-1,4-dicarboxylate dianion helps to stabilize the crystal structure.
