Abstract: The (H₂O)(C₁₀H₈N₂)Ni(C₈H₄O₄) portion of the title compound, [Ni(C₈H₄O₄)(C₁₀H₈N₂)(H₂O)]·3H₂O, adopts a layer architecture in which the dianionic entity chelates to the Ni atom [Ni-O = 2.053  (5) and 2.056  (4)  Å, and O-Ni-O = 91.5  (2)°]. The two chelating O atoms, a water molecule [Ni-O = 2.083  (5)  Å], the carboxyl O atom from an adjacent dianion, and the N atoms of two 4,4'-bipyridine heterocycles comprise the octahedron around the Ni atom. Adjacent layers are linked into a network motif by hydrogen bonds.
