Abstract

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(C28H20N2O2)]·2CH2Cl2, (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.
