Dichloridobis(2-{1-[2-(1H-indol-3-yl)ethyl­iminio]eth­yl}phenolate-κO)zinc(II)–2-{1-[2-(1H-indol-3-yl)ethyl­iminio]eth­yl}phenolate (1/2)

摘要

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.
