摘要

The reaction of 2,2'-bipyrazine (bpz) and Cu(NO₃)₂ with addition of HCl gave a new complex [Cu₅(bpz)₂Cl₁₀(H₂O)]_n nH₂O, with bpz serving as a μ₃-ligand to link three different copper centers. X-ray crystallography shows a self-assembled supermolecule formed by [Cu₅(bpz)₂] repeating unit further bridged through Cl^-. This is the first Cu(bpz) complex which possesses extended topology instead of closure. Magnetic susceptibility measurements for this complex from 2 to 300 K reveal weak antiferromagnetic interactions between copper(II) in agreement with out-of-plane exchange pathways and large Cu-Cu separation.
