One-dimensional copper polymers with pentadentate diazine ligands

One-dimensional copper(II) polymers [(Cu4L2)(NO3)4]n (1) and [(Cu4L2)Cl4]n (2) (H2L = salicylaldehyde-2-pyridinecarboxyl-hydrazone) were achieved via self-assembly. The Cu⋯Cu separations were ca. 2.90 and 4.75 Å for the phenoxide oxygen bridged pair and the N–N bridged pair with antiferromagnetic spin exchanges between Cu(II) ions.

Two new one dimensional copper(II) polymers based on tetranuclear units was achieved via self-assembly from N3O2 pentadentate ligand and structurally characterized.Figure optionsDownload as PowerPoint slide
