The mol-ecule of the title compound, [Co(C8H6NO4)2(H2O)4], is centrosymmetric. It is a cobalt(II) complex, bearing two (2-nitro-phen-yl)acetate and four aqua ligands. The coordination around the Co(II) atom is distorted octa-hedral, defined by four O atoms of water mol-ecules in the equatorial plane and by two carboxyl-ate O atoms at axial positions. The dihedral angles between the benzene ring and the acetate and nitro groups are 61.90 (10) and 19.21 (11)°, respectively. The water mol-ecules form O-H⋯O hydrogen bonds with the nitro and carboxyl-ate groups, leading to a layered structural arrangement parallel to (001).
标题化合物[Co(C₈H₆NO₄)₂(H₂O)₄]的分子具有中心对称性。它是一种钴(II)配合物，带有两个(2-硝基苯基)乙酸酯和四个水配体。Co(II)原子周围的配位环境为扭曲的八面体，赤道平面上由四个水分子的O原子定义，轴向位置由两个羧酸根O原子定义。苯环与乙酸酯和硝基之间的二面角分别为61.90 (10)°和19.21 (11)°。水分子与硝基和羧酸根基团形成O-H⋯O氢键，导致形成平行于(001)的层状结构排列。
