Abstract: The title compound, [Ni(C₇H₃NO₄)(H₂O)₄]·2H₂O, was obtained by the reaction of nickel nitrate with 2,5-pyridinedicarboxylic acid (molar ratio 1:1) in water. The compound contains a six-coordinate Ni^II ion, which is bonded to the N atom and an O-C group of the carboxylate group in the 2-position of the 2,5-pyridinedicarboxylate ligand, and four water O atoms. Intermolecular hydrogen-bonding interactions are present, linking the nickel complex and water molecules in the crystal structure.
