The mol-ecule of the title compound, [NaNi(C(18)H(18)N(2)O(4))(C(2)N(3))(H(2)O)], is approximately planar, with a maximum deviation from the mol-ecular plane of 0.770 (5) Å. The coordination environment of the Ni(2+) ion is distorted square-planar and it is N(2)O(2) coordinated by the 6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate Schiff base ligand. The Na(+) atom is chelated by the four O atoms of the Schiff base ligand, a water ligand and a dicyanamide anion. The structure displays inter-molecular O-H⋯N hydrogen bonding.
标题化合物[NaNi(C₁₈H₁₈N₂O₄)(C₂N₃)(H₂O)]的分子近似平面，与分子平面的最大偏差为0.770(5) Å。Ni²⁺离子的配位环境为扭曲的平面正方形，由6,6'-二甲氧基-2,2'-[乙烷-1,2-二亚基双(次氮基甲基亚基)]二酚盐席夫碱配体进行N₂O₂配位。Na⁺原子被席夫碱配体的四个O原子、一个水配体和一个双氰胺阴离子螯合。该结构呈现分子间O-H⋯N氢键。
