Self-assembling tetranuclear copper(II) complex of a bis-bidentate Schiff base: double-helical structure induced by aromatic π···π and CH···π interactions

Abstract

The synthesis and structure of a tetranuclear copper(II) complex of a bis-N,O-bidentate Schiff base is reported; two types of copper(II) centers and the preference for two conformational degrees of freedom in the ligand lead to the unique formation of a novel supramolecular architecture not requiring a preorganized synthetic approach.
