Syntheses and Magnetism of Binuclear Cu( Ⅱ )—Ni( Ⅱ ) Complexes with N,N-bis (N-hydroxyisopropyl-ethyleneamine ) -oxamido as Bridging Ligand

摘要

The complexes with extended bridged structure are of current interest due to understanding some insight into the pathway of electron transfer in biological system and obtaining some useful information about designing molecular-based magnets. Many papers dealing with oxamido as multi-atom bridges have been published. It has been revealed by the variable-temperature magnetic susceptibility investigations that the long-range magnetic coupling occurs between the paramagnetic centers bridged by this kind of ligand. But, to our knowledge, there are few studies on the substituent R(as shown in Fig. 1) being non hydrogen.
