The title compound, [Co(C(22)H(18)N(2)O(4))]·2CH(2)Cl(2), was isolated from the reaction of N,N'(o-phenyl-ene)bis-(vanillalimine) (H(2)L) with Co(SCN)(2). The crystal structure contains a Co(II) ion surrounded by the L(2-) ligand in a slightly distorted square-planar fashion. Inter-molecular C-H⋯O hydrogen-bonding contacts between the dichloro-methane solvent mol-ecules and the meth-oxy or carboxyl-ate O atoms are observed in the crystal structure. The planar complex mol-ecules stack through inversion related π-π inter-actions between the six-membered rings of the vanillalimine half ligands. The distance between centroids is 3.498 (2) Å and the perpendicular distance is 3.345 Å. A partial stacking is observed with a centroid-centroid distance of 3.830 (2) Å, a perpendicular distance of 3.350 Å and a slippage of 1.856 Å.
标题化合物[Co(C₂₂H₁₈N₂O₄)]·2CH₂Cl₂是由N,N'-(邻亚苯基)双(香草醛亚胺)(H₂L)与Co(SCN)₂反应分离得到的。晶体结构中，Co(II)离子被L²⁻配体以略微扭曲的平面正方形方式包围。在晶体结构中观察到二氯甲烷溶剂分子与甲氧基或羧酸根O原子之间存在分子间C—H⋯O氢键接触。平面的配合物分子通过香草醛亚胺半配体六元环之间的反演相关π-π相互作用堆积。质心之间的距离为3.498(2) Å，垂直距离为3.345 Å。观察到部分堆积，质心-质心距离为3.830(2) Å，垂直距离为3.350 Å，滑移为1.856 Å。
