中文摘要：
合成了1个稀土金属Tb-氮氧自由基配合物Tb（hfac）3（NITPhOH）2（hfac：六氟乙酰丙酮;NIT-PhOH：2-（4-羟基苯基）-4,4,5,5-四甲基咪唑啉-3-氧化-1-氧基自由基）.X-射线单晶衍射分析结果表明,该化合物属正交晶系I222空间群,晶胞参数a=1.228 2（3）nm,b=2.874 0（6）nm,c=3.255 1（7）nm,α=β=γ=90°.Tb（Ⅲ）离子为八配位模式,2个氮氧自由基以单齿端基配体的形式分别以氮氧基团的氧原子与Tb（Ⅲ）离子配位,形成了十二面体的结构.配合物的变温磁化率研究显示,配合物中Tb（Ⅲ）离子与氮氧自由基之间存在弱的铁磁相互作用.
英文摘要：
A novel complex [Tb（hfac）3（NITPhOH）2] was synthesized and characterized structurally and magnetically（hfac=hexa uoroacetylacetonate,NITPhOH=2-（4′-hydroxyphenyl）-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide）.It crystallizes in Orthorhombic,space group I222,with a=1.228 2（3） nm,b=2.874 0（6） nm,c=3.255 1（7） nm.Each Tb（Ⅲ） ion is coordinated by two oxygen atoms from two NITPhOH radicals and six oxygen atoms from three different hfac anions to form eight-coordinated dodecahedron geometry.The variable magnetic measurement shows that there is weak ferro magnetic interaction between Tb（Ⅲ） ion and NITPhOH radical.
