In the title compound, [Ni(C(10)H(6)NO(3))(2)(H(2)O)(4)], the central Ni(II) atom is located on an inversion center and coordinated in a slightly distorted octa-hedral geometry by two O atoms from two 2-oxo-1,2-dihydro-quinoline-4-carboxyl-ate ligands and four water mol-ecules, all of which act as monodentate ligands. The crystal structure features an extensive network of inter-molecular hydrogen-bonding inter-actions (O-H⋯O and N-H⋯O) and offset face-to-face π-π stacking inter-actions [centroid-centroid distances = 3.525 (3) and 3.281 (5) Å].
在标题化合物[Ni(C₁₀H₆NO₃)₂(H₂O)₄]中，中心Ni(II)原子位于一个对称中心上，由来自两个2-氧代-1,2-二氢喹啉-4-羧酸酯配体的两个O原子和四个水分子以稍微扭曲的八面体几何构型配位，所有这些都作为单齿配体。晶体结构具有广泛的分子间氢键相互作用（O-H⋯O和N-H⋯O）和错位的面对面π-π堆积相互作用[质心-质心距离 = 3.525 (3) 和3.281 (5) Å]。
