摘 要：Because the molecule-based magnetic materials can provide fundamental insight into interesting magnetic phenomena and are with potential application in magnetic devices,the molecular magnetism has always been a frontier research area during the past decade. Among which,due to the excellent magnetic transferring ability between the paramagnetic metal centers and the comparatively easy prediction of the magnetic coupling nature mediated by the cyanide bridge,the cyanide-bridged magnetic complexes have been given intense attention in the molecular magnetism field,and such intention have also led to many progress in this field.[1-3]The polyaza macrocyclic ligands with some rigid character obtained by condensation of 2,6-diacetylpyridine and polyamine,which are usually coordinated to the equatorial plane of metal ions with only two trans replaceable sites weakly bonded to other ligands,have been proved to be good ancillary ligands to assemble low-dimensional structural cyanide-bridged *** incorporating 3 d paramagnetic metal ions Mn(Ⅱ),Co(Ⅱ),Fe(Ⅱ),Fe(Ⅲ),Ni(Ⅱ),*** these types of macrocyclic ligands,a few of low-dimensional magnetic complexes with interesting magnetic properties have been *** two-dimensional cyanide-bridged Fe-Ni coordination polymer has been successfully prepared with the polyaza macrocyclic compound[Ni(L)](Scheme 1) as assemble segment,and structurally and magnetically characterized.
