In the mononuclear complex molecule of the title compond, [ZnCl2(C18H18N2O)2]·2C18H18N2O, the Zn atom, which lies on a twofold rotation axis, is coordinated by phenolate O atoms in a tetrahedral 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 intramolecular 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 interaction. The CH2—CH2 group in the uncoordinated Schiff base is disordered equally over two positions.
