Indolin-2-one (oxindole), (I), undergoes a Knoevenagel condensation with ferrocene-1,1'-dicarbaldehyde, (II), to afford the title complex 3,3'-[(E,E)-ferrocene-1,1'-diyldimethylidyne]diindolin-2-one dichloromethane disolvate, [Fe(C(28)H(20)N(2)O(2))]·2CH(2)Cl(2), (IV). The structure of (IV) contains two ferrocene complex molecules in the asymmetric unit and displays, as expected, intermolecular hydrogen bonding (N-H···O=C) between the indolin-2-one units. Intermolecular π-π stacking interactions are also observed.
吲哚 - 2 - 酮（氧化吲哚），（I），与二茂铁 - 1,1'- 二甲醛，（II），发生克诺文纳格尔缩合反应，得到标题配合物3,3'-[(E,E)-二茂铁 - 1,1'- 二亚甲基二亚甲基]二吲哚 - 2 - 酮二氯甲烷溶剂合物，[Fe(C₂₈H₂₀N₂O₂)]·2CH₂Cl₂，（IV）。（IV）的结构在不对称单元中包含两个二茂铁配合物分子，并且如预期的那样，在吲哚 - 2 - 酮单元之间显示出分子间氢键（N - H···O = C）。还观察到分子间π - π堆积相互作用。
