In the title complex, [Ni(C(26)H(22)N(2)O(4))], the Ni(II) atom has a slight distortion toward tetra-hedral geometry from a square-planar structure, coordinated by two O and two N atoms of the tetra-dentate salen-type bis-oxime 2,2'-[1,1'-(ethyl-enedioxy-dinitrilo)diethyl-idyne]di-1-naphtholate (L(2-)) unit, with a mean deviation of 0.022 Å from the N(2)O(2) plane. The N- and O-donor atoms are mutually cis. The dihedral angle between two naphthalene systems of the L(2-) ligand is 67.59 (4)°. The crystal structure is stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions, which link neighbouring mol-ecules into extended chains along the b axis.
在标题配合物[Ni(C₂₆H₂₂N₂O₄)]中,Ni(II)原子从平面正方形结构向四面体几何形状略有扭曲,由四齿salen型双肟2,2'-[1,1'-(乙二氧基二氮杂环丁烷)二乙撑]二-1-萘酚盐(L²⁻)单元的两个O原子和两个N原子配位,与N₂O₂平面的平均偏差为0.022 Å。N供体原子和O供体原子相互呈顺式。L²⁻配体的两个萘环系统之间的二面角为67.59 (4)°。晶体结构通过分子间的C-H⋯O和C-H⋯π相互作用得以稳定,这些相互作用将相邻分子沿b轴连接成延伸链。
