- 中文摘要: A series of binuclear copper(II) complexes containing.alpha.-diimine ligand has been synthesized and characterized by electron paramagnetic resonance spectroscopy. The copper complexes of the form.lbrak.Cu(dien)L'.rbrak.(CIO/sub 4/)/sub 2/ or.lbrak. Cu/sub 2/(dien)/sub 2/L.rbrak.(CIO/sub 4/)/sub 4/, where dien is diethylenetriamine, L' is monodentate ligand and L is bridging ligand, were studied. The EPR spectra were recorded in solution and frozen glassy solution. In the frozen solution spectra , the values of g/sub .dbar./ are in the range of 2.10 to 2.20, and the g/sub .perp./ are in the range of 2.03 to 2.06. Furthermore, the values of A/sub .dbar./ are in the range of 170 to 188 gauss, and the A/sub .perp./ are in the range of 17 to 32 gauss. The data indicate that the structure of Cu(II) complexes is axial symmetry in square pyramidal form.
