摘　　要：合成了一种新的取代苄基吡啶盐 [NCBzPy]Cl( 1 ) ,1和NiCl2 ,dmit2 -反应生成分子基磁体 [NCBzPy][Ni(dmit) 2 ]( 2 ) ,其结构用元素分析、IR和UV进行了表征。并测定了 2在 2K～ 3 0 0K的变温磁化率 ,结果显示 ,相邻Ni3 + 之间存在铁磁偶合作用。A new substituted benzylpridiniums [NCBzPy]Cl was synthesized, futher, a molecule-based magnet [NCBzPy][Ni(dmit) 2] was synthesized and characterized by elemental analysis, IR and UV spectra. Its magnetic susceptibility data has been measured in the temperature range of 2K～300 K, and the results indicated that there exist ferromagnetic coupling interactions between neighbor Ni(Ⅲ) ions.
