The Electron Spin Resonance(ESR) spectra of ten 5-formazanyl copper(II) complexes in toluene solutions have been observed at room temperature and at that of liquidnitrogen.The ESR(g and A) and bonding (α2) parameters of the copper ion were greatly affected by substituting several groups at the ortho position of 1-phenyl ring of formazan.Based on these results, the complexes are classified into three groups: Group I, in which A ca. 0.012-0.013 cm-1 and α2 ca. 0.5; Group II, in which A ca. 0.017 cm-1 and α2 ca. 0.7, and Group III, in which two copper ions are interacting.It is clarified that they correspond nicely to three types of copper-containing proteins previously investigated.
