In the mononuclear complex mol-ecule of the title compond, [ZnCl(2)(C(18)H(18)N(2)O)(2)]·2C(18)H(18)N(2)O, the Zn atom, which lies on a twofold rotation axis, is coordinated by phenolate O atoms in a tetra-hedral coordination geometry. The coordinated Schiff base uses its indole NH donor site to form a hydrogen bond to the negatively charged phenolate O atom of the uncoordinated zwitterionic Schiff base. There is an intra-molecular N-H⋯O hydrogen bond in the coordinated and uncoordinated Schiff bases. The indole NH site of the uncoordinated Schiff base does not engage in a hydrogen-bond inter-action. The CH(2)-CH(2) group in the uncoordinated Schiff base is disordered equally over two positions.
在标题化合物[ZnCl₂(C₁₈H₁₈N₂O)₂]·2C₁₈H₁₈N₂O的单核配合物分子中，位于二重旋转轴上的Zn原子通过酚盐O原子以四面体配位几何构型配位。配位的席夫碱利用其吲哚NH供体位点与未配位的两性离子席夫碱带负电荷的酚盐O原子形成氢键。在配位和未配位的席夫碱中存在分子内N-H⋯O氢键。未配位席夫碱的吲哚NH位点不参与氢键相互作用。未配位席夫碱中的CH₂-CH₂基团在两个位置上无序分布，占有率相等。
