Abstract: In the title complex, [Ni(H₂O)₆]L₂·2H₂O, where L is p-nitrobenzoate (C₇H₄NO₄), each Ni^II cation lies on an inversion center and is octahedrally coordinated by six water molecules. The L^- anions do not coordinate to the nickel, but act as counter-anions. The crystal structure is composed of alternating layers of [Ni(H₂O)₆]²⁺ cations and L anions. The [Ni(H₂O)₆]²⁺ cations, water molecules and L^- anions are connected through a complex pattern of hydrogen-bonding interactions, resulting in a three-dimensional network.
