Abstract: In the title compound, [Ni(C₁₀H₆NO₃)₂(H₂O)₄], the central Ni^II atom is located on an inversion center and coordinated in a slightly distorted octahedral geometry by two O atoms from two 2-oxo-1,2-dihydroquinoline-4-carboxylate ligands and four water molecules, all of which act as monodentate ligands. The crystal structure features an extensive network of intermolecular hydrogen-bonding interactions (O-HO and N-HO) and offset face-to-face - stacking interactions [centroid-centroid distances = 3.525 (3) and 3.281 (5) Å].
