新型叠氮桥联的六核镍的合成结构及磁性研究

Reaction of nickel acetate tetrahydrate with Schiff base 2-[(pyridin-2-ylmethylimino) methyl] phenol (HL) in methanol-water solution, adding with NaN3 as the bridging ligand, yields the complex [Ni(L)(μ1,1-N3)H2O]6⋅H2O (1). The X-ray structure determination shows that the complex is nearly a perfect hexagonal structure and the temperature (2-300 K) dependent magnetic susceptibility indicates it possesses ferromagnetic behavior.
