The title complex, [Ni(C(18)H(18)N(2)O(4))(H(2)O)], lies on a mirror plane with the Ni(II) ion coordinated by two N and two O atoms of a tetra-dentate Schiff base ligand and one water O atom in a distorted square-pyramidal enviroment. The -CH(2)-CH(2)- group of the ligand is disordered equally over two sites about the mirror plane. The dihedral angle between the mean planes of the two symmetry-related chelate rings is 37.16 (6)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link complex mol-ecules into one-dimensional chains along [100] and these chains are linked, in turn, by very weak inter-molecular C-H⋯O hydrogen bonds into a two-dimensional network.
标题配合物[Ni(C₁₈H₁₈N₂O₄)(H₂O)]位于一个镜面平面上，Ni(II)离子由一个四齿席夫碱配体的两个N原子和两个O原子以及一个水分子的O原子配位，处于扭曲的四方锥环境中。配体的-CH₂-CH₂-基团在镜面平面两侧的两个位置上无序分布，占有率相等。两个对称相关螯合环的平均平面之间的二面角为37.16 (6)°。在晶体结构中，分子间的O-H⋯O氢键将配合物分子沿[100]方向连接成一维链，这些链又通过非常弱的分子间C-H⋯O氢键连接成二维网络。
