摘      要：A novel 1D copper（II） helical chain is constructed through the connection of tetranuclear copper（ll） units [Cu4（L）（Py）4] （H8L=N,N＇-（BINOL-3,3＇-dicarboxyl）-disalicylhydrazide, where BINOL is 1,l＇-binaphthalenyl-2,2＇- diol, py=pyridine） by weak coordination-driven self-assembly, and characterized by IR, single crystal X-ray dif- fraction, thermogravimetric analysis, and X-ray power diffraction analysis. Interestingly, the helical chains are packed in an alternating left-（M） and right-handed （P） chirality, the orientation of the helices was determined by the axial chirality of the ligand. The complex shows antiferromagnetic interactions between the copper centers.
