K.-B. Shiu, C.-H. Yen, F.-L. Liao and S.-L. Wang

Abstract: The title compound, trans-[Ni(C₃H₄N₂)₄(H₂O)₂]Cl₂, was obtained by the reaction of nickel chloride, succinic acid, imidazole, and NaOH (molar ratio 4:2:8:3) in water. The compound contains a six-coordinate Ni^II ion lying on an inversion center, which is bonded to four imidazole N atoms and two water O atoms. Intermolecular hydrogen-bonding interactions are present, linking the nickel complex cations and chloride anions in the crystal structure.
